Here are some lessons I’ve learned from a not so “Really Successful Knitted Squares Collaboration Blankets” project, and a simple pattern I’ve made so yours will be more successful. Or even just for you to do a knitted blanket made from garter stitch squares that is easy to sew together. You can make the square with any yarn and in any gauge and to any size you like.

This square looks good all one colour and half one colour/half the other colour. Have a look, for example, at all the quilt designs for half-square triangles! Self-patterned and ombre yarns work well too. Stripes are good but you’ll have more ends to weave in. Also, if you carry the yarn up the selvedges for stripes they are much fussier to sew together.

I’ve also provided examples and guidelines for variations and a useful grid for printing out so you can plan your own design.
