i KNOW FOR HISTORICAL PURPOSES PLASTIC IS NOT ALWAYS IDEAL BUT IF YOU ARE CONCERN USE A LAYER OF TISSUE PAPER (WHITE) TO COVER THE PLASTIC. I STORE ALL OR MOST IN PLASTIC AND HOPEFULLY USE IT IN THIS MILLENIUM, (HA-HA-HA). i NEED A LICENSE PLANT THAT SAYS I BRAKE FOR QUILT STORES, OR MAKE A MAP ON QUILTS STORES I LOVE TO VISIT. TALK ABOUT ADDICTION!!!!!
