Guess we all have a litle bit of "Scrooge" in us. I save medicine bottles for straight pins, safety pins and needles. The smaller one are great for thimbles, also. I save Wash & Wipe boxes for buttons and plastic fruit jars # 5 microwave safe for freezer containers. I buy sliced peaches in those jars. I also save a plastic coffee can to put bit and pieces of veggies in for soup. Since I want my scrap stash out of the way, I have a very long pillow case into which I throw my scraps. Attached to it is a smaller pillow case for trims, thread, etc used in making a quilt.
What I won't do to save some $$$$$.
