Yay...I finished my large Pressing board. I followed Sharon Schamber's video on You Tube. It uses 5/8 width OSB board cut to the size you need, 100% cotton canvas and 100% cotton batting(warm and natural). Layered on my kitchen table, canvas first, batting second,sprayed with spray adhesive, then the board. stapled, put it on the top of a table I bought at WalMart, sprayed really much with water and will let it dry tonight to shrink any ridges out, and is ready to go tomorrow! Hardest part was lifting it onto the table. Thanks for everyone's advice, I appreciated it.
