I would like to try fusible webbing but I need someone to recommend one to use where I don't have to sew the edges. I will be making a wall hanging and will be fusing four 8'1/2x 11 pieces on a piece of a fabric. Any help will be appreciated.

For a wall hanging, I'd probably use Steam-a-Seam2 (both sides are sticky and both sides fuse, allowing for temporary placements until you decide to permanently fuse with iron).

Heat N Bond Super is a type of fusible that is permanent and you do not sew the edges. Just be sure to keep the left-over separate from any sewable fusible you have. The Super will gum up your needle if you try to sew with it.

Unless you are using a thick fabric Heavy Heat Bond pleads thru...I use Lite and also Pellon Wonder Under fusible webbing
