you all have given me some good ideas. live in a rural area so few thrift stores, but will stop by Walmart & Dollar Tree tomorrow to see what I can find. Also maybe the one business supply store--but it' small. I have an appointment in the city next week & if I can't find anything locally I'll got by the big box stores. I agree that I don't want them stacked on top of each other or leaning at an angle though.
