I now stock Hobbs Fusible Cotton wadding - (it is actually 80% cotton & 20% polyester)
I have been using this fusible wadding for approx ten years in bags, wall hangings, quilts etc.
It is fantastic to use as no pinning or tacking is needed!!! You just layer it up between your top & backing as normal & press on both sides using a steam iron on cotton setting. It doesn't matter if you have to layer just one piece of fabric and wadding on the ironing board as it will not leave any residue and will not stick to the ironing board.
Great for hand or machine quilting.
It is also great for using as a design wall - purchase a piece for the quilt you are working on & iron your blocks in place as you make them. You can even fold it up & put it away with your blocks in place.
It is also repositionable, if you have a wrinkle then lift up your fabric lay it back down & re -iron. If your piece is coming unstuck around the edges then again just re iron.
I have it on the roll measuring 96" wide. The cost is £13.00 per meter but you can order any quantity of metres.
