I am quite proud that I found colours that exactly match the colours in our sofa. I ran out of the light red yarn in the middle of the project, but luckily still found it in a Wolle Rödel at the lake of constance. Each square took nearly exactly 1 ball of yarn. I knitted the last square which you can see at the upper right corner of the picture with the leftovers - this is the square I like most now! It is just plain stockinette with a border of 5stiches garter stich at each side
