You can easily sew blocks for babies or young children. Choose sturdy fabric in different colours. Keep in mind that babies put everything in their mouth so the fabric should be not be fluffy and should be prewashed and colour safe. Baby skin is very sensitive so a sturdy cotton material would work well.

Cut out squares of a size of your choice, suggested, four or five inches, again remembering that they must be big enough not to fit in baby's mouth. You will need six squares for each block. Make each square a different colour; bright colours, pastels, prints, or pictures.

If your fabric does not fray, you can whipstitch the edges together making stitches small enough so that fingers can not fit in the stitches. If your fabric does fray, sew the edges by machine or by hand. Assemble your block into a cross shape, then sew up each side. Stuff with cotton batting and sew on the top square.
