Yesterday I made the yo-yos so I could finish this little project off.
I used one of these yo-yo makers which made it very easy indeed. In fact I timed myself, and to make one yo-yo took just five minutes (the fabric was already cut in squares ready to go) including threading the needle, gathering up the yo-yo and knotting the threads off at the end.
It took a bit longer to attach them to the block and was quite a fiddly job, I decided to finish off the yo-yos with some cute little buttons. All it needs now is a little hanger so I can hang it up in my sewing room.
