(I used some leftover yarn from the "rainbow blanket".)
I could not finish the whole block because I ran out of blue (needed to add about 10 more rows). So I just ended it with a couple of white rows and cast off. Even without those last rows it's still about 23.5 cm across.
I'm sure I'll be making a pillow or blanket using this pattern (for my new sofa!).
I didn't really know what to do with this trial block but Ade wanted to use it in a frame and hang it as art in her home, so that's where it's going
