Stitch witchery is a web of thread that comes in little rolls of different widths. I believe mine is a 1/2" wide roll. You can fold in two edges of fabric and place the stitch witchery in between. Then, all you have to do is place a damp cloth and top and hold the iron on it for 10-20 seconds. It makes a pretty good bond that you have to tug on pretty hard to pull apart. I wouldn't leave it at just that, but it really does help hold in stubborn edges until you can place a top stitch across it.
Here are a few "in the process" pictures :) I'll post a final once I finish up. The strap is all that is left.
^First place the Fusi-Boo between the two pieces of fabric
^Then turn in the rough edges and place stitch witchery in between. Hold the iron it it (dampened first) for 10 seconds.
^ I reinforced the top of the pocket (the part that will not be attached) so that it will have a stronger hold.
^I then top stitched the pocket onto the lining of the side panel.
^This is the finished product of the panel lining.
For now, God Bless!
PS. I got a new camera, from my wonderful fiance! It is the Canon EOS Rebel T2i ... He got me the body, two lenses, a very nice backpack style case, 16 GB class 10 SDHC card, UV filter, and it was all given with love :) I really can't wait to take some pictures and do a little post-developing in lightroom.
