I-Baggie Tablet Knit Case [FREE Knitting Pattern]

If you’ve ever tossed your tablet into a bag and held your breath hoping it wouldn’t come out scratched, cracked, or worse, you already know exactly why a padded knit case is worth making. The I-Baggie Tablet Knit Case is one of those satisfying, practical projects that takes only a weekend to complete, costs very little in materials, and ends up being something you reach for every single day. Whether you’re protecting a 10-inch iPad, an Android tablet, or an e-reader, this cozy knitted sleeve wraps your device in a thick, cushioned layer of handmade love.

The best part? This pattern is completely free, and it’s suitable for knitters of all skill levels. If you can knit, purl, and cast on, you have everything you need to make this project. Let’s dive in.

Why Knit a Tablet Case?

Before we get into the pattern itself, it’s worth talking about why a knitted tablet case is such a good idea in the first place. Store-bought tablet cases are almost always made from synthetic materials — hard plastic, thin neoprene, or stiff faux leather. They do the job, but they don’t have personality, they don’t stretch gently around your specific device, and they certainly don’t come with the satisfaction of having made them yourself.

A knitted case made with a medium-weight or bulky yarn creates a surprisingly effective buffer against bumps and drops. The natural give of a knitted fabric means your tablet slides in and out without effort, yet the case holds its shape around the device snugly enough that nothing rattles around. If you use wool or a wool-blend yarn, you get the added benefit of a fiber that has a natural memory and resilience — meaning it bounces back after compression rather than staying squashed.

There’s also the customization factor. You can knit this case in your school colors, match it to your favorite bag, add your initials with duplicate stitch after the fact, or choose a textured stitch pattern to give it a more tactile, interesting look. The I-Baggie is designed as a straightforward, rectangular sleeve, which means the canvas is completely yours to decorate as you see fit.

Materials You’ll Need

One of the most appealing things about this pattern is how minimal the supply list is. You probably already have most of what you need in your stash.

Yarn: You’ll need approximately 150–200 yards of a medium-weight (worsted) or bulky yarn. A yarn with some elasticity works best, so anything with a percentage of wool, alpaca, or acrylic with stretch properties is ideal. Avoid very stiff cotton for your first attempt, as it can make the seaming a bit tricky — though cotton does create a beautiful finished object once you get the hang of it.

Needles: US size 7 (4.5mm) for worsted weight, or US size 9 (5.5mm) for bulky weight. You can work this flat on straight needles or in the round on circular or double-pointed needles, depending on your preference. The flat version is slightly easier for beginners since it involves simple knit and purl rows and then a seam at the end.

Notions: A tapestry needle for seaming and weaving in ends, a tape measure, scissors, and optionally a stitch marker or two if you’re working in the round.

Optional: A button, snap, or piece of Velcro for the closure. The pattern includes a simple flap that can be left open or secured with your preferred closure method.

Gauge and Sizing

Getting your gauge right is the single most important step in ensuring your case fits your specific tablet. Because tablets come in a wide range of sizes, this pattern is designed around a measurement system rather than a one-size approach.

Suggested gauge for worsted weight: 18 stitches and 24 rows = 4 inches in stockinette stitch.

Suggested gauge for bulky weight: 14 stitches and 20 rows = 4 inches in stockinette stitch.

Before you cast on, measure your tablet’s width and height. Add about half an inch to one inch to each measurement to account for ease — you want the tablet to slide in comfortably without the case being so loose that it offers no protection. Write down these adjusted measurements; you’ll use them to calculate your stitch count.

For example, if your tablet measures 6.5 inches wide and 9.5 inches tall, your adjusted measurements might be 7 inches wide and 10 inches tall. Using a worsted gauge of 4.5 stitches per inch, you’d cast on approximately 32 stitches and work to approximately 10 inches in length before beginning the flap.

Don’t skip your gauge swatch. It takes 15 minutes and it will save you from knitting an entire case that’s either too tight to get your tablet in or too roomy to protect it.

The I-Baggie Pattern: Step by Step

Cast On

Using your chosen yarn and needles, cast on the number of stitches you calculated based on your tablet’s width plus ease. If you’re making a standard 10-inch tablet case in worsted weight, a cast-on of approximately 44 stitches works well as a starting point. Adjust up or down based on your personal gauge.

For a neater bottom edge, use a long-tail cast on. If you haven’t tried it yet, this is a great pattern to learn it on — it creates a firm, tidy edge that looks beautiful at the base of the case and adds a subtle extra layer of durability right where your tablet rests.

Body of the Case

The body is worked in your chosen stitch pattern. The simplest option is stockinette stitch — knit on the right side, purl on the wrong side — which creates a smooth, classic fabric that stretches gently both horizontally and vertically.

If you want a bit more texture and structure, seed stitch (knit one, purl one, alternating each row so the stitches are offset) creates a beautiful nubby fabric that is slightly thicker than stockinette and doesn’t curl at the edges, which is a real advantage when you’re working flat.

For a more advanced look, a simple 2×2 rib (knit two, purl two, repeated to the end of the row) creates a stretchy, cozy fabric that hugs your tablet snugly. Just note that ribbing tends to pull in, so you may need to add a few extra stitches to account for the reduced width.

Work in your chosen stitch pattern until your piece measures the height of your tablet plus ease. If your tablet is 9.5 inches tall and you’re adding 0.5 inches of ease, you’ll work until the piece is 10 inches long measured from the cast-on edge.

The Flap

Once your body is the correct length, it’s time to create the flap that folds over the top of the tablet to keep it secure.

Continue in your stitch pattern for an additional 2.5 to 3 inches. This creates a generous flap that covers the top of your tablet and can be tucked in or secured with a button.

If you’d like a rounded or shaped flap rather than a straight one, you can decrease one stitch at each end every other row for the last inch of the flap. This creates a gentle taper that looks a bit more tailored.

Buttonhole (Optional)

If you plan to use a button for your closure, you’ll want to add a buttonhole near the end of the flap. To do this, work to the center stitch or to the position where you’d like your button, then work a simple yarn-over buttonhole: knit two together, yarn over. On the next row, work the yarn-over as a regular stitch. This creates a small, clean hole that works beautifully with a medium-sized button.

If you prefer a snap or Velcro, skip this step and sew your closure onto the finished case.

Bind Off

Bind off all stitches loosely. A stretchy bind-off method is worth using here — the standard bind-off can sometimes create a tight edge that doesn’t allow the flap to fold over comfortably. A simple way to get a looser bind-off is to use a needle one or two sizes larger for this row only.

Finishing the Case

Seaming

Fold your finished rectangle in half lengthwise so the cast-on edge meets the row you worked to before starting the flap. The flap should extend above the fold. If you worked in stockinette, fold the piece with the purl side (wrong side) facing out so that when you seam and turn it right-side out, your seams are hidden inside.

Using your tapestry needle and a length of yarn, seam the two side edges together using mattress stitch. This seaming technique creates an almost invisible join on the right side of the fabric, which gives your case a polished, professional look. Work slowly and pull the yarn gently — you want a firm seam without puckering.

If you worked in seed stitch or another reversible stitch pattern, you can seam with either side facing out since there’s no “wrong” side to hide.

Once both sides are seamed, turn the case right-side out and give it a gentle tug to even out the seams.

Weaving In Ends

Thread your tapestry needle with each yarn tail and weave it in along the seam line or through the backs of several stitches, changing direction once to lock it in place. Trim any excess. Take your time with this step — a well-finished case is worth the extra few minutes it takes.

Blocking

For wool or wool-blend yarn, a light blocking can make a significant difference in the finished look. Soak the case in cool water with a drop of wool wash, gently press out the excess water without wringing, and then ease the case into shape and lay it flat to dry. Slide your tablet (or a similarly sized book or flat object) inside the case while it dries to help it hold the correct dimensions.

Acrylic yarns don’t benefit from wet blocking, but you can use a steam iron held slightly above the surface to help smooth out any unevenness in the fabric.

Adding the Closure

Sew your button onto the body of the case, positioned so that the buttonhole on the flap aligns with it when the flap is folded down. If you’re using a snap, sew each half onto the corresponding point on the flap and the body of the case. If you’re using Velcro, cut a small strip and sew or glue it into position.

Stitch Pattern Variations

One of the most fun things about a simple rectangular pattern like this is how many different looks you can achieve just by changing your stitch pattern. Here are a few ideas to get you started.

Diagonal Rib: Cast on a multiple of four stitches, then work knit two, purl two on the first row. On each subsequent row, shift the pattern one stitch to the right. After a few rows, you’ll see a lovely diagonal texture developing across the fabric.

Moss Stitch: Similar to seed stitch, but worked over two rows rather than one. On row one, knit one, purl one across. On row two, knit one, purl one across in the same alignment. On row three, purl one, knit one across. On row four, purl one, knit one across. Repeat these four rows. The result is a chunkier, more defined texture than seed stitch.

Garter Stitch: Simply knit every row. This is the easiest possible stitch pattern and creates a reversible, slightly ridged fabric that doesn’t curl at all. Perfect for a very beginner-friendly version of this project.

Simple Cable Panel: If you’re comfortable with cables, adding a six-stitch cable panel down the center of the case looks absolutely stunning and adds very little time to the project. Work the cable cross every six rows for a classic twisted rope effect.

Color and Yarn Ideas

The yarn choices for this project are practically limitless, but a few combinations are especially lovely.

A single-color case in a deep jewel tone — forest green, navy, burgundy, or rich teal — has a timeless, sophisticated look that goes with everything. Choose a smooth yarn to showcase a textured stitch pattern, or a slightly rustic yarn with character (like a tweedy wool) if you’re working in stockinette.

Stripes are another wonderful option and don’t require any stranded colorwork techniques. Simply change colors at the beginning of a row, carry the unused yarn up the side, and you’ll have a cheerful striped case in no time. Two-row stripes are bold and graphic; wider stripes of varying widths have an artisan feel.

If you’re feeling more adventurous, you can work a simple colorblock design by knitting the lower half of the case in one color and joining a second color for the upper half and flap. The color change point sits right at the fold, creating a clean visual line.

Tips for Success

A few final thoughts before you cast on that will make your knitting experience smoother and your finished case more polished.

Measure twice, knit once. Take the time to really measure your tablet carefully, add your ease, and swatch before you begin. A case that doesn’t fit is frustrating, and with a project this small, there’s no reason to skip this step.

Keep your tension consistent throughout. Tension changes are most visible in stockinette, so if you tend to knit more loosely when you’re tired or distracted, this is a good project to work on when you’re fresh and focused.

Use stitch markers to mark the center of your piece if you’re adding a cable panel or a centered buttonhole. It only takes a second and it removes a lot of guesswork.

If you’re seaming for the first time, practice on a small swatch before tackling the real thing. Mattress stitch is intuitive once you get the hang of it, but it helps to see the technique on a piece you don’t mind practicing on.

Finally, enjoy the process. This is a small, satisfying project that works up quickly and produces something genuinely useful. Knit it while watching a movie, listening to a podcast, or sitting in your favorite chair on a rainy afternoon. The I-Baggie is the kind of pattern that reminds you why you started knitting in the first place — because making things with your hands feels good, and the things you make are worth carrying with you every day.
