I had originally been inspired by this project and was going to do 6 more squares to fill in the middle. But now I'm looking at it and I'm not sure
(Please ignore that I'm clearly unable to arrange the squares in a straight line! I had a little helper out of shot so was trying to be quick!)
I favourited this amazing blanket a while ago when I browsing on ravelry. But I have 4 x 5 big squares whereas she had 5 x 5 so the centre could be a single giant square.
I might have an idea though, I think I'll play around for a bit to see if it will look right ;-) Crossing my fingers!
