I remember a story (true story) that mom told about some cousins. Many years ago 2-3 ladies were working together and decided to make a double wedding ring quilt. They cut their cardboard templates and proceeded to trace around them with pencil. Then they started cutting out the pieces with scissors. After sewing some parts together they discovered that the sections didn't fit together! What they finally discovered was that they had used the same cardboard templates for ALL the tracing and pressing the pencil along the sides gradually wore away the sides and the last pieces traced were small than the first ones traced. I don't know what they did with those useless pieces of fabric. I doubt if they knew about crumb quilts! Moral of the story, when using cardboard templates...make several sets and don't use each set too long!!! Long live plastic templates!!!!
