Every time you look at this optical illusion afghan you will see something different!
The original was made in Aran weight yarns though you can use any yarn of your choice. The yarn you choose may alter the overall size but you can add extra blocks if you wish.
It is very easy to make, worked entirely in garter stitch, using one yarn at a time on a small number of stitches.
The booklet comes complete with a colouring-in sheet so you can plan your own colour choices.Read the story of Window Boxes on Woolly the Thoughts web site.
