I Am A Toy Designer And This Is The Knitted Frog That I Made

There is something quietly magical about holding a finished handmade toy for the first time. You turn it over in your hands, squeeze it gently, check that the eyes are level, and then — if you’re anything like me — you put it on the shelf and just stare at it for a few minutes. After years of working as a toy designer, that feeling has never gone away. And the knitted frog sitting on my worktable right now might be the project I’m most proud of in recent memory.

I want to walk you through the whole thing: the inspiration, the design process, the materials, the knitting itself, and everything I learned along the way. If you’re a knitter curious about toy design, a toy designer curious about knitting, or just someone who loves frogs and handmade things, I think you’ll find something useful here.

How This Project Started

I didn’t plan to design a frog. I was working on a commission for a child’s nursery — a set of woodland creatures — and frogs kept showing up in my mood board. I pinned image after image of them: poison dart frogs with their electric blues and yellows, fat little tree frogs clinging to glass with their round toe pads, cartoon frogs with enormous eyes and wide smiles. Something about the shape of a frog is almost perfectly suited to knitted toys. They’re round and soft. Their limbs can be floppy without looking wrong. Their faces invite an expression.

I’ve been designing stuffed animals and knitted toys professionally for about eleven years. My work usually falls somewhere between functional toy and decorative object — things that feel sturdy enough to hand to a three-year-old but considered enough to sit on an adult’s bookshelf. The frog needed to hit that same balance. It needed to be squeezable and lovable, but it also needed to look like I’d thought carefully about it.

I started with pencil sketches, which is always where I begin. No software, no mood board refinement, just a sketchbook and a mechanical pencil on a Sunday afternoon.

The Design Sketches

Frog anatomy is deceptively interesting. Real frogs have wide, flat heads, enormous eyes positioned on top of the skull, and hind legs that fold back along their body in a very specific way. If you try to translate all of that literally into a knitted toy, you end up with something that looks alien rather than charming. The trick is identifying which anatomical details communicate “frog” to a viewer’s brain and leaning into those, while softening or abstracting everything else.

For me, the key features were: the wide mouth, the round prominent eyes, the chunky hind legs, and a body that reads as “compact and round” rather than flat. I sketched probably thirty variations over two evenings. Some were too realistic — they felt cold and reptilian. Some were too cartoonish — they looked like frog costumes rather than frogs. The sketch I landed on had a body roughly the shape of a slightly squashed sphere, eyes that sat high and forward on the head (positioned more like a cartoon than like real frog anatomy, but more believable), short front arms with mitten-like hands, and long hind legs that bent at the knee and could be posed slightly.

One decision I made early was to give the frog a closed, slightly upturned mouth rather than an open grin. Open-mouthed toy frogs are everywhere. They always look a little aggressive or manic to me. A closed mouth with a gentle upward curve reads as serene and friendly, which felt right for a nursery piece.

Choosing Materials

I take material selection very seriously, especially for anything going near young children. For this project I wanted a yarn that was soft enough to press against a cheek without any scratchy fiber, durable enough to survive washing, colorfast (because children are unpredictable), and available in a green I actually liked.

The green question took longer than I expected. There are a lot of greens in the knitting world. There are yellow-greens that look acidic and slightly nauseous. There are dark forest greens that feel more Christmas than frog. There are muted sage greens that are fashionable but don’t read as “frog” immediately. What I wanted was a clear, medium green — the green of a healthy fern frond, or of a new leaf in early May. Bright enough to be cheerful, saturated enough to photograph well, but not so electric that it would exhaust the eye.

I ended up working with a DK-weight merino blend. Merino was an easy choice: it’s soft, it has a slight natural elasticity that gives knitted fabric a pleasant give, and it washes well on a gentle cycle. The blend included a small percentage of nylon, which adds durability without changing the feel significantly. I chose a coordinating pale cream for the belly, and a rich, dark olive green for the pupils and some detail work on the legs.

For the eyes, I used safety eyes in a size that I felt was slightly larger than strictly necessary — 18mm. Big eyes read as “young” and “friendly” to human viewers, thanks to the same instincts that make us find babies and kittens appealing. It sounds calculating, but toy design has always had an element of working with human perceptual psychology, and I make no apologies for using large eyes deliberately.

The stuffing was a polyester fiberfill — hypoallergenic, washable, and capable of being packed to different densities in different parts of the toy. I stuff the body quite firmly for structure, the head slightly less firmly so it has a gentle squish, and the limbs more loosely so they can be posed and draped naturally.

Drafting the Pattern

I draft all my patterns by knitting swatches first. This sounds obvious but I know many designers who work out the math theoretically and then knit a whole prototype only to find the gauge is wrong. I knit a 6-inch swatch, measure it carefully under the same tension conditions I’ll use for the toy, and build all my calculations from there.

For this frog I was working at 22 stitches and 30 rows to 4 inches in the round on 3.25mm needles. From that baseline I could calculate the circumference of the body, the dimensions of the head, and the proportions of the limbs.

The body is knitted in the round from the cast-on at the base. I use a combination of increases and decreases to shape it into something rounder than a plain tube — there’s a series of paired increases worked over several rounds early on to push the belly out into a more spherical profile, then a long straight section through the middle, then decreases to close the top. The belly panel is worked as a separate flat piece and seamed on afterward, which I know is considered unfashionable in some knitting circles (seamless construction is very popular right now), but for toy work I actually prefer the slight firmness that a seam adds to the underside. It gives the toy a better base to sit on.

The head is constructed separately in the round, shaped similarly to the body but with a flatter base. Before closing it up, I insert the safety eyes. This is always a slightly nerve-wracking moment — once those posts are locked on the inside, repositioning requires tools and determination. I measure twice with a ruler and mark the position with a removable stitch marker before committing.

The mouth is embroidered after assembly using a single strand of dark green yarn and a curved running stitch that I go over twice to give it definition. The nostrils are two small French knots.

The legs were the most technically interesting part of the pattern to draft. The hind legs needed to read as “frog legs” — that characteristic fold where the femur points outward from the body and the lower leg angles back down. I achieved this with short rows worked into the upper leg section, which creates a natural bend without requiring a separate knee joint. The toe pads are small stuffed bobbles worked individually and then attached to the foot, which sounds fiddly and is, but the result is worth it. They give the foot a very satisfying texture and immediately communicate “amphibian” in a way that a plain rounded foot would not.

The front arms are simpler: short tubes with a slightly enlarged “hand” at the end, closed with a gathered cast-off. They’re attached at an angle so they look like the frog is sitting with its arms resting slightly forward, an alert and interested posture.

Knitting It

I knit the body over the course of about three evenings while rewatching a television series I’d already seen. Knitting for me is often a background activity — something I can do while my hands stay busy and my mind wanders. The body and head together took perhaps eight hours of knitting time. The legs, with their short rows and bobble toes, took longer: probably five or six hours just for the four limbs. The assembly — seaming, stuffing, attaching limbs, embroidering the face — took another two hours.

Total knitting and assembly time was somewhere around sixteen to eighteen hours for the finished prototype. When I refine and knit a second version, I can typically shave twenty to thirty percent off that time because I’m not stopping to measure, re-measure, make notes, or rip back confused sections of the pattern.

One thing I always note in my process journal: where I ripped back, and why. For this frog, I ripped back the top of the head twice. The first time, my decreases were too abrupt and the crown of the head looked pinched rather than round. The second time, I’d corrected the decreases but worked them on the wrong rounds and created an unexpected ridge. The third attempt was right. These failures are not frustrating to me anymore — they’re data. Every mistake tells you something precise and useful about what the pattern needs.

The Finished Frog

Sitting here looking at it, the frog is about 22 centimeters tall in its natural seated position. It’s the color of a garden in May. Its eyes are wide and dark and slightly solemn, which I like — there’s a quiet watchfulness to it that I didn’t fully plan but appreciate. The belly is cream-colored and smooth. The legs fold in the right places. The toe pads are ridiculous in the best possible way.

It has a name, by the way. The child for whose nursery it was commissioned has already decided: his name is Ferdinand. I think that’s exactly right.

What I’ve Learned About Designing Knitted Toys

Over the years, a few principles have stayed consistent across every toy I’ve designed.

Proportion matters more than detail. A toy with slightly wrong proportions will never look right no matter how beautiful the face embroidery is. Get the overall shape and the relationship between body parts correct first, and the details will fall into place.

Texture is an underused tool in toy design. The contrast between the smooth stockinette of the frog’s back and the slight purl texture I used on the interior of the legs, and the bumpy bobble toes, gives the toy a physical richness that a single-texture design wouldn’t have. Knitting offers an extraordinary range of textures that toy designers coming from other disciplines often don’t fully exploit.

Safety is non-negotiable. If a toy is going to a child under three, it needs to pass scrutiny for choking hazards, sharp edges, and secure attachment of all small parts. My rule is simple: if I have to pull harder than I think a determined toddler could, it’s not safe enough. I redo the attachment.

Make the second one before writing the pattern. Every toy I’ve designed has a first prototype that I knit from messy notes, and a second prototype that confirms the pattern works as written. The second version always reveals ambiguities and errors in the written instructions that I didn’t notice when I was constructing the first one from my own mental model. Writing a pattern is a separate skill from knitting a toy, and it requires the perspective of someone reading it cold.

Photography is part of the design. I realize this sounds more like a business observation than a design principle, but in the current landscape it’s genuinely true that how a finished toy photographs affects how it’s perceived. I style my finished toys on neutral backgrounds with good natural light and photograph them from multiple angles. The frog looks particularly good from slightly above and to one side, which shows the rounded top of the head, both eyes, the belly, and the toe pads in a single frame.

Will I Release This Pattern?

Yes, with some caveats. I’m currently in the process of refining the pattern document — adding clearer instructions for the short-row knee technique, improving the notes on stuffing density, and having two test knitters work through it independently. I aim to release it through my pattern shop in the next few weeks. If you’re interested, the best way to hear about it is to subscribe to my newsletter or follow along here.

I’ve been debating whether to include a modification for a larger version — perhaps 30cm rather than 22cm — which would be easier to knit for beginners because the pieces would be more forgiving. I think I will include it as an optional section with adjusted stitch counts.

A Final Thought

There’s a reason handmade toys endure. In a world where almost any object can be manufactured cheaply at enormous scale, there is still something that a handmade toy offers that a factory cannot replicate: the specific decisions of a specific person, working through a problem with yarn and needles and patience, producing an object that carries that attention in its very fiber.

Ferdinand the frog exists because someone sat down and thought about frogs for several evenings, tried things that didn’t work, tried again, and eventually produced something that is right. Not perfect — I can see a place where my tension wobbled slightly near the left eye, and the second toe pad on the right front foot is fractionally smaller than the others — but right. Alive in the way that handmade things are alive.

That’s why I do this. And that’s the frog I made.
