Rag Mat  We use Crescent© Mat boards exclusively. Mat boards are buffered with an  alkaline to stop acid leeching from the paper.   Rag mats are made from cotton. Not all rag mats are the same. Some dyed rag mats are acidic and a buffered barrier paper is added to the reverse. Same backing paper that is added to regular mat board. 100% cotton rag mat only comes in a few light colors.  Rag mat that is available in many colors cost a lot of money, but a buffered barrier paper is still needed to protect your work.     Make sure you are purchasing the type of mat board that you want.   An informed stitcher is a happy stitcher.                Tomorrow’s Heirlooms Are Created Today
