Oh I totally want to make some for after my baby is born! They are so cute

Super simple - I had a couple of charm packs and just picked 6 squares, you sew four squares together in a row, sticking the folded ribbons in which ever seams suit you, all the raw edges lined up (make sure you really reinforce the stitching over the ribbon, I had one come loose on my "test" block). Then at the second square from one end of your row of four, add one more square on each open side (again, with ribbons if you choose), then you sew the sides to make it a cube shape (again, ribbons, if you wanna). Leave enough of the top open to turn it, turn it, stuff it, stitch it closed and Done! You can find tutorials online for making fabric blocks, I just put my own twist on it! And my son (and the other babies) LOVE them! They're fun to play with and chew on!
