My sil quilts and we love to talk about quilting but we don't quilt together. She is a night person and I am a day person! My mom began quilting about the same time I did. We lived apart for many years and just talked quilts. Then 3 years ago I moved near her and Dad after Mom had a bit of a stroke. Together we completed two quilts Mom had started for family members. Then Mom decided it was time to stop and sil and I helped her clean out her stash. I have several away friends who quilt that we compare notes. Since moving here I now have new quilting friends and am just now becoming aware of several others who are interested. There is just something about quilting that just wants to be shared with others!
It would be a wonderful thing if your DD and DIL slowly developed a desire to quilt. I have two daughters who live one and two days away. They both like cross stitch and knitting and crochet....no quilting yet.
