As I've been making quilts for all those in my very small congregation, they seem to want queen size quilts. The single folks though ask for lap size and even those I make around 60x70 or a bit larger depending on their size. I also have yet to make a quilt for my bed which is only a full size bed since I sleep with just my furbabies. Even so, as it's an antique bed, I've replaced the old mattresses which has made it a bit higher off the ground and if I want to make it go down to the floor, it will still be a fairly large quilt............someday. I already know it's going to be a French Braid pattern as I've never made one before and I like to try new patterns to me.
As for the queen size quilts, they usually end up between 100 to 108 inches going both directions. Right now I have 8 of these bad boys waiting to be quilted as I lost my sewing mojo during the summer and have yet to get it back but it's coming as I can feel it.
