Today I'm going to show you what interfacings I put inside them and give you a different way to do the drawstring closure that is under the flap of the backpack above.
This is what you need to know. IF you do the drawstring through a casing as the pattern instructs DON'T put interfacing on the casing piece because it works better if it is soft. But, if you plan to use grommets then that piece NEEDS interfacing to support the grommets.
This opening is then slip stitched or whip stitched closed.
That's it on the backpacks ... I've got to start packing for Costume Con!!! So much to do!
