I have made a ton of wedding quilts these last couple of years. (my 3 daughters and a lot of their friends have all gotten married)
I usually go to their registry and find the colors they have chosen for their home. A couple of them I asked their parents what their favorite colors were. So far, everyone has loved the quilts that I have made.
My daughters have not gotten their quilts yet. Those will be queen size (I give large lab/twin quilts as gifts) and they are picking out the main fabrics and the pattern (with guidance)The first two have their picked out and fabrics set aside. I just need to enlarge both of the patterns because, of course, the patterns were not queen size (sigh)
