Thank you for making the effort to donate your wife's stash and supplies. It can be such a blessing. I inherited my sister-in-laws stash 12 years ago and I am still using her fabric in quilts. I have made quilts for her children and grandchildren. It is so special to hand a quilt to one of these special ones and to say this fabric or that square is from her stash.
Find a local quilt guild or two or three and share the blessings and know that your wife's passion will be honored with many, many quilts for others.
