I was asked to make two more mac cases for my other daughter and her husband...|I thought they were joking, I couldn't imagine my son in law would want one but he did. They gave me the measurements and colours that they would like. I cut strips, joined them together, quilted wadding to the back and sewed up the side leaving enough for a flap at the top. I then made an inner bag for the lining. Fitted it in place and sewed up around the edge. Adding a button and loop to fasten.
