Lynnie, the way I look at it is....to buy more fabric I have to use some of what I have. So I enjoy cutting into my treasures. The fabric will never make it into a project unless I use it, so this thinking works for me. So I give you permission cut and use those treasures, then when you see some fabric you can't live without you can buy it.
oh, forgot to add I love your quilt Dotty. I agree, there are going to be some beautiful quilts this ride.
