Picky? No! I shop the thrift stores for sheets and tablecloths, books, teapots and VCR's and never walk out empty handed. I get more fabric in one sheet than in 5 men's shirts and it all matches ----- use them for backings ----- and each sheet costs me a grand total of $1.50. Some of the fabric is cotton/poly and it wears like iron and is no problem handquilting. I'm always amazed at the brand new items that people simply throw away ......... unbelievable! The one thing that I do is to donate a large trash bag stuffed full of goodies on each day that I go "treasure hunting" ...... makes DH happy that way.
