Frankenyarn Blanket Part 4 | Free Crochet Pattern
If you’ve been following along with the Frankenyarn Blanket series, welcome back — and if this is your first time joining us, you are in for such a treat. This is Part 4 of the ongoing free crochet pattern series that has become one of my absolute favorite projects to share with this community. The whole concept behind the Frankenyarn Blanket is beautifully simple: we use up all those leftover yarn scraps, partial skeins, and odds and ends sitting in your stash to create something warm, cozy, and completely one-of-a-kind. No two Frankenyarn Blankets will ever look alike, and that is exactly what makes this project so magical.
If you haven’t checked out Parts 1, 2, and 3 yet, I highly recommend going back and reading through those first. They cover the foundation of the blanket, the stitch patterns we’ve been working with, and how to manage your yarn transitions smoothly. That said, Part 4 is designed to stand beautifully on its own as well, and the section we’re tackling today adds incredible texture and visual interest to the overall piece.
Grab your hooks, dig into that yarn stash, and let’s get started.
What Is the Frankenyarn Blanket?
For those of you who are new here, the Frankenyarn Blanket is a stash-busting crochet blanket that uses a rotating mix of yarn weights, colors, and fiber types to create a patchwork-style, wonderfully textured throw. The name comes from the idea of stitching together a beautiful monster — just like Frankenstein’s creature — from mismatched pieces that somehow come together into something greater than the sum of their parts.
The beauty of this blanket is that it is completely forgiving. There are no strict color requirements, no matching yarns needed, and no pressure to buy anything new (unless you want to, of course). You can use acrylic, wool, cotton, blends — whatever you have on hand. The varying textures and weights actually add to the charm of the finished blanket rather than detracting from it.
This series has resonated with so many of you, and I’ve loved seeing the photos in our community group. Every single blanket looks different, and all of them are stunning in their own unique way.
Materials You’ll Need for Part 4
Since this is a stash-busting project, the yarn list is intentionally flexible. Here’s what you’ll want to have on hand as you work through this section:
Yarn: Any combination of worsted weight, bulky, or chunky yarn scraps. If you’re mixing weights significantly, you may need to adjust your hook size slightly as you transition between yarns. I’ll walk you through that as we go.
Crochet Hook: Size 5.5mm (I/9) as your base hook. Keep a 6.0mm (J/10) and a 5.0mm (H/8) nearby for adjusting tension with different yarn weights.
Yarn Needle: For weaving in ends as you go — and with a Frankenyarn project, you will have plenty of ends to weave in. Doing this as you work rather than saving it all for the end will save your sanity.
Scissors: Always close by.
Stitch Markers: Optional but helpful for keeping track of pattern repeats in today’s new stitch section.
Measuring Tape: For checking your gauge and overall blanket dimensions as you grow the piece.
Gauge
Because we’re working with mixed yarns and this is a stash-busting project, gauge is less critical here than it would be for a fitted garment. However, for reference, the sections worked in standard worsted weight yarn on a 5.5mm hook should produce approximately 14 stitches and 16 rows per 4 inches in the basic single crochet stitch.
Don’t stress too much about matching this exactly. The nature of the Frankenyarn Blanket means your dimensions will vary slightly from mine, and that is perfectly okay. The goal is a cozy, large throw-sized blanket, and we’re getting there one stitch at a time.

dc — double crochet
hdc — half double crochet
sk — skip
st(s) — stitch(es)
sp — space
RS — right side
WS — wrong side
rep — repeat
blo — back loop only
flo — front loop only
yo — yarn over
pm — place marker
Where We Left Off
At the end of Part 3, you should have a blanket panel that measures roughly 24 inches wide and somewhere between 18 and 24 inches in length, depending on how many yarn sections you worked. We left off having just completed a textured ridge section using back loop only single crochet, which created those beautiful raised horizontal lines across the fabric.
If your blanket is a slightly different size, don’t panic. This is a living, breathing project, and the instructions for Part 4 are written in a way that adapts to whatever dimensions you’re working with. We’re adding to the length of the blanket today, so your stitch count across the row should remain the same as it was at the end of Part 3.
Part 4: The Brick Stitch Section
The star of Part 4 is the Brick Stitch — sometimes called the Offset Shell or the Stepped Shell — which creates a gorgeous woven, textured look that mimics the look of a brick wall laid on its side. The pattern is simple enough that it works up quickly once you get the rhythm, but it looks incredibly intricate when finished. This is one of those stitches that will have people asking if you bought the blanket at a boutique.
The Brick Stitch works in multiples of 3 plus 1, so you’ll want to confirm that your stitch count fits this multiple before beginning. If it doesn’t, you can add or subtract one or two stitches at the end of your last row from Part 3 to adjust. A few stitches either way won’t be noticeable in the grand scheme of the blanket.
Yarn Color and Weight Notes for This Section
For the Brick Stitch section, I recommend choosing two or three yarns that complement each other for a slightly more cohesive look in this section, since the stitch pattern itself is what we want to show off. That said, if you want to go full Frankenyarn chaos mode and change colors every row or two, the stitch still works beautifully — it just becomes a more colorful, energetic section of the blanket.
This is also a great place to use up those partial skeins that only have enough yardage for five or six rows. The Brick Stitch transitions between colors at the end of a row, so swapping yarns is seamless and natural.
The Brick Stitch Pattern
Foundation: This section begins directly on the last row of your Part 3 panel. You should be ready to work across the right side of your piece.
Row 1 (RS): Join your yarn in the first stitch with a standing sc. Sc across to the end of the row. Turn. (Your full stitch count)
Row 2 (WS): Ch 1, sc in each st across. Turn.
Row 3 (RS) — Brick Row: Ch 3 (counts as first dc), skip the first st, dc in the next st. Skip 1 st, dc in the next 2 sts. Repeat from across to the last 2 sts. Skip 1 st, dc in the last st. Turn.
Row 4 (WS): Ch 3 (counts as first dc), dc in the space before the next dc pair. *Dc in the space between dc pairs across. Dc in the last space, dc in the turning chain. Turn.
This is where the “brick” effect begins to appear. The pairs of double crochets in Row 4 sit nestled in the gaps created by Row 3, creating that beautiful offset pattern.
Row 5 (RS): Ch 3, skip the first st, dc in the next st. Skip 1 st, dc in next 2 sts. Rep from across, ending dc in top of turning ch. Turn.
Row 6 (WS): Repeat Row 4.
Continue repeating Rows 5 and 6 until your Brick Stitch section measures approximately 6 to 8 inches, or until you’ve used up the yarns you designated for this section. You can make this section as long or as short as you like — the beauty of the Frankenyarn Blanket is that it grows at your own pace.
Finishing Row: To smooth the top edge of the Brick Stitch section before moving on, work one row of sc across all stitches. This creates a clean, flat foundation for whatever stitch pattern comes next in Part 5.
Changing Yarn Colors in the Brick Stitch Section
If you’re changing colors partway through the Brick Stitch section (which is very encouraged!), the cleanest way to do it is at the end of a row. Work your last stitch until two loops remain on your hook, then pull through with the new color. This creates a neat color change that blends cleanly into the edge of your work.
If you’re working with a yarn that’s running out mid-row, you can join the new yarn in the same way mid-stitch, then weave in both ends securely on the wrong side when you’re done. With a Frankenyarn project, a few mid-row color changes are part of the charm.
Adding a Popcorn Accent Row
One of my favorite tricks for adding extra texture and personality to the Frankenyarn Blanket is to throw in an accent row here and there using a fun stitch like the popcorn stitch. After your Brick Stitch section is complete and you’ve worked your smoothing row of sc, try this optional popcorn accent before beginning the next yarn section.
Popcorn Row: Ch 3, dc in the first st (counts as first popcorn — complete by dropping the loop from your hook, insert the hook from front to back through the top of the ch-3, pick up the dropped loop and pull through to close the popcorn). Sc in the next 2 sts, make a popcorn in the next st (work 5 dc in the stitch, drop the loop from your hook, insert the hook from front to back through the first dc of the group, pick up the dropped loop and pull through). Repeat from across, ending with sc in the last st. Turn.
Work one row of sc after the popcorn row to smooth things out, then you’re ready for your next yarn transition.
This row is optional but it adds such a fun dimensional element to the blanket. In the photos I’ve shared on my Instagram, you can see exactly where these little popcorns pop up across the surface of the blanket — they’re absolutely delightful.
Helpful Tips for Managing Your Frankenyarn Stash
Working through a project like this brings up some practical stash management questions, and over the course of this series I’ve learned a few things that make the process much smoother.
Organize by weight, not color. When pulling yarns for a session, sort them into piles by weight first. This makes it easier to plan which yarns to work consecutively and when to adjust your hook size.
Keep a yarn journal. Jot down which yarns you’ve used, roughly how much, and in what order. If you ever want to recreate a similar blanket or troubleshoot a tension issue, having these notes is invaluable.
Embrace imperfection. There will be rows that look slightly looser or tighter than others. There will be colors that feel a little awkward together at first. Trust the process. Once the blanket is finished and washed, everything relaxes and blends together in the most wonderful way.
Weave in ends as you go. I know I’ve said this already, but it bears repeating. With a project that involves this many yarn changes, trying to weave in a hundred ends at the end of the project is genuinely demoralizing. Five minutes of weaving at the end of each session makes the finishing process so much more enjoyable.
Don’t be afraid to frog. If a section doesn’t look right to you or a yarn isn’t working, it’s okay to rip it out and try something different. The Frankenyarn Blanket is a low-stakes, high-reward project, and every section should bring you joy.
How Much Yarn Do You Need for Part 4?
This is always a tricky question with a stash-busting project, but here’s a rough guideline. For the Brick Stitch section alone, working a blanket that’s approximately 24 inches wide, you’ll use roughly 150 to 250 yards of yarn depending on the stitch rows you complete. Since double crochet rows use more yarn than single crochet rows, plan accordingly.
If you’re working with scraps that are less than 50 yards each, you’ll likely go through three to five different yarns in this section, which is perfectly fine. Just keep those colors coming and let the blanket tell its own story.
What’s Coming in Part 5?
Part 5 is going to be so fun. We’re going to introduce the Larksfoot Stitch (also called the V-stitch variation) into the blanket, which creates a delicate, lacy look that balances out all the dense texture we’ve been building. It’s a lovely contrast to the Brick Stitch section, and it’s the perfect place to use up those thin or lace-weight yarns you might have floating around in your stash.
We’ll also be talking about how to add a simple border to tie the whole blanket together, because at some point this beauty is going to be finished, and I want it to look like the masterpiece it truly is.
