it depends on the blocks - what design are you using? You can use a zig zag stitch, a satin stitch or you can stitch them by hand - can you show us your blocks? *4U
When i get them stiched out. I was looking thorugh my designs last night and decided that would be something I could do and not have to sit right on the machine while I do my other work. then when I got all the squares done, I'd sew them together.
