About the Overlay Mosaic Crochet Blanket
I designed this blanket last year to celebrate the 10th birthday of AllFreeCrochet – I was so excited when they asked me!
Oliver was still really little at the time and I was still really struggling with PTSD after my husband was really unwell and this pattern helped me so very much to start designing again and to fall back in love with crochet.
It’s the perfect stash buster (all of the yarn in it is from my own stash, and yes, I do have a large stash!) and it was great as a project to make just a row or two of at a time.
It’s only a four-row repeat and you change colour nice and regularly so is really fun to do too!
So, if you’re looking for a stash busting, uplifting, rhythmical and plain good fun pattern then this one might be for you.
This crochet blanket pattern is a free crochet pattern in both UK and US terms on the blog for everyone to enjoy, just scroll down to find it.

Any colours from your stash will do really well that create a similar rainbow scheme – you’ll need around 500g of an equivalent yarn.
A great alternative if you’d rather not use cotton is Swish Worsted by WeCrochet (100% superwash merino), or Paintbox Simply Aran (100% acrylic) which both come in a great range of colours.
Tension and Sizing
The finished blanket will be 82cm by 74cm
14st and 12 rows = 10cm by 10cm but tension is not essential
Along with your yarn, you will need the following:
- 5 mm (US H) crochet hook – my favourites are Furls Streamline Swirl crochet hooks or Clover Amour crochet hooks.
- Tapestry Needle
- Stitch Markers
Glossary and Abbreviations
ch – chain
ss – slip stitch
sk – skip
BL – back loop
FL – front loop
rep – repeat
RS – right side
dc – double crochet
tr – treble
sc – single crochet
dc – double crochet
A ch1 at the beginning of a row does not count as a stitch.
Work in the back loop of stitches throughout.
Always work from the RS (right side) of the piece. At the end of each row, break the yarn and return to the 1st stitch of that row with RS facing to start the next row.
Leave tails long enough to create a 6cm fringe on either end of your work.

This pattern showed up on Pinterest on a site called Ribblr, and wanted you to be aware. I don’t see that site on your list, so wondered if it was copyright infringement.

This pattern is just beautiful! I’m brand new to mosaic crochet but this looks like something I can make. I would like to make something smaller to start, though, maybe placemats. Do you happen to know what the pattern repeat is so that I can alter the size? I can usually figure it out with “regular” crochet but not sure how with this. Thank you very much for your help.
