I'm really liking this 'quilt as you go' technique! It is pretty labour intensive but let's face it - you are doing the yucky hard work part at the front end in a non hard work kind of way. And it's much easier to get these little blocks under your needle than a queen size quilt!
Here is my first block, it's made from Japanese inspired fabrics and I'm going to try and do 4 and join them to make a cushion cover. It's a little wonky but I like it. And it's very very easy to do. You could even make them extra wonky if you wanted to.
