This combo is a game changer. Add in a tailor’s clapper and take your pressing to a new level!! I leave this right by my machine so that I can chain piece and then press quickly and get right back to sewing. The wool mat presses your block from both sides because wool holds heat, so you get flatter crisper seams that you would with a traditional ironing board. The Oliso irons are great and this mini one is perfect for pressing seams. I use it for everything except ironing large cuts of fabric or whole quilts.
