You can make the squares like this:
Chain 4, join to make a ring, ch 3 (counts as dc), make 3 dc in ring, ch 2, *4 dc in ring, ch 2* three times, join to top of beginning ch 3, fasten off, weave in ends!
My squares came out to about 1.5" each. Make 64 of these.
Sew squares together in an 8 x 8 pattern. Weave in all loose ends.
