Hello Grandpa and welcome from Germany. I don't have a very big stash either. On the other hand I found out that having lots of crafty things puts pressure on me, b/c it feels like I HAVE to do something with it NOW to me. Just my HO.
Some weeks ago I asked friends and family to weed through their mens shirts, which makes wonderful quilting fabric.
At Hancocks I bought Kona Cotton in Snow White for very little money, this goes with everything b/c it "ties" all colours together.
