Candace, yes I machine appliqued the edges. As far as turning under, I did that where possible. These were the first blocks my mother ever made and were had stitched together with some very irregular seams. In a few cases I had to applique raw edges to end up with the hexagons anywhere near the proper size/shape. But it was worth the effort -- she had kept these with her for 70 years through about 10-12 moves, some up-sizing, others downsizing ending up in a one room apartment in assisted living. They must have been extremely important to her. I made four wall hangings out of them, one each for my two daughters, my sister and myself.
