Quilting presentation
Do a demo of how a block is made, from the cutting with the rotary cutter to the quilting. The power point requirement could be be briefest of the steps involved. If you don't have to use clipart, skip it. To save time you could do the demo
in steps that are mostly predone like is done on the TV presentations. Have the finished product to show. Do the whole thing like you were talking to a nonquilter friend.
