my mother made me a beautiful double wedding ring quilt. she had it quilted by the amish. the pencil markings for the quilting are so very DARK that we haven't even attempted to get them out and it had been 2 good years now. please help us with some suggestions for this mess. we hope that there is still some simple solution. we are located in cold old southern ohio----would it be better to tackle this in the spring or summer????? thanks to you great quilting friends....... :-D
