The Little Acorns mosaic crochet blanket square is a perfect project to try out some mosaic crochet.
Using only basic crochet stitches and simple colorwork, you will have a modern fall square in no time!
This square is part of the Cozy Fall Charity Makealong hosted by Knitting with Chopsticks and Noor’s Knits.
Read on to find out all about the MAL and to get this little square pattern 🙂
Cozy Fall Charity Makealong
Each day between Oct 4 – Oct 29, a brand new crochet AND knitting square pattern will be released.
You can find out all you need to know about the Make-Along here:

And if you would like to get a head start on your blanket (or simply don’t want to check back each day for the new squares), you also have the option to purchase theCozy Fall Charity Makealong Bundle.
This bundle contains all of the blanket square patterns, and as this is a charity event, 50% of the proceeds from each purchase will be donated to the non-profit organization Cure Childhood Cancer.
Mosaic Crochet Blanket Square
For my contribution to the Cozy Fall Makealong, I decided to create a mosaic crochet square using two, fall-themed colours.
If you haven’t tried mosaic crochet before, then this little square is a great jumping off point.
The colorwork repeat is very, very simple; honestly, after a couple of rows, you probably won’t even need to consult the written instructions or colorwork chart anymore!
Note: the print-friendly PDF version of this pattern also includes a mosaic crochet colorwork chart, in addition to the written instructions below.

Crochet Blanket Square Pattern
Abbreviations (US Terms)
- ch = chain
- st = stitch
- sk = skip
- sl st = slip stitch
- sc = single crochet
- dc = double crochet
- beg = beginning
- rem = remaining
- C1 = Color 1
- C2 = Color 2
- RS = Right Side
- WS = Wrong Side
This square is worked in rows from the bottom up, finishing with a trim of sc sts around the edge of the square.
- Ch 1 at the start of each row does not count as a stitch.
- The stitch count for each row is given in [ ] at the end of the row. If no stitch count is given, then the count is the same as the previous row.
- N.B. For all C2 rows, “ch 2, sk next st” counts as ONE stitch.
- This square is worked using the “overlay” mosaic crochet technique.
- Rows are worked as a pair e.g. Row 1a, Row 1b, Row 2a, Row 2b etc
- Each pair is worked in a single color – there are no “mid-row” color changes.
- You can either follow the written instructions in the pattern below, or use the colorwork chart in the print-friendly PDF.
- At the end of each “b” row, change color on the last yarn over of the last sc, and then begin the next “a” row with the new color.
- Between row pairs, do not cut yarn unless instructed to do so; you will simply float the new yarn up as required for each color change.
Mosaic Crochet Charts
- Starting in the bottom right corner, read the chart from the bottom upwards as follows:
- read “a” rows from right to left
- read “b” rows from left to right
- For C1 “a” rows:
- a C1 square with a C2 square underneath it → sc
- a C1 square with another C1 square underneath it → dc in the skipped st of the SAME color 3 rows below
- For C1 “b” rows:
- sc in each st (whether it is a sc or a dc)
- For C2 “a” rows:
- a C2 square with a C1 square underneath it → sc
- a C1 square indicates “ch 2, sk next st”
- For C2 “b” rows:
- work as for the previous C2 “a” row
