Your quilt is really very nice, I love how you designed it!
Did you use any batting or just the fabric and the denim? I have made quite a few and am always amazed at the weight.
The last one I made was for my son and I just sewed the blocks together and lined it with a beautiful flannel desert fabric. It was the first one I made with out any batting and he says it is really warm. It was for a double bed and it was really heavy. (they have to take it to laundrymat to wash as it is too heavy for their machine!
I get jeans at second hand stores and use the pieces I can't use for the quilt for purses or aprons. I love working with jeans!
