I do the same as Diannia. I wash and dry the flannel - cut a 36 inch square, round the corners (using a plate), serge the edges then crochet a shell stitch around the edge. I have a whole stock pile of these blankets - some done by my Mother- these are for my grandkids when they have their babies. I buy my flannel when Hancock's has the fabric on sale for $2.00 per yard! I have 4 left to crochet around this year. Have never done two fabrics.
