If you have used the wrong Heat/Bond weight or put it on the wrong side of the fabric, here is a cheap and easy way to remove
If you have one of the Teflon applique sheets (Joannns has them) simply peel the paper off of the bonding source which is now stuck to the fabric-lay the Teflon applique sheet on top and hold your hot iron on it -checking to see when it losens. Continue till it all sticks to the sheet. Then you can scrape the HeatnBond off of the Teflon applique sheet
I have been reading posts for a while but never written to the group-I hope that I am doing this right
