The newest product for Quilters from Sew Easy is the 100% Pure New Zealand Wool Ironing Mat in 3 sizes, 10" x 10" for those smaller projects such as EPP, 17" x 17" for all patchwork piecing and 17" x 24" for your work table. Essential for any Project where precise creases and seams are necessary, can be used with or without steam and grips fabric as you iron. Wool is naurally heat resistant so it repels heat back into your fabric, essentially ironing your piecing from both sides. From experience we suggest using an old towel or sheet underneath your mat to catch condensation, just from Gails observations.
