I've been meaning to update this bag base tutorial for a while. Not only was the original hastily put together from a black & white pdf document (long story involving band width), but I've ever-so-slightly changed my method since it was written. (And colour is always nicer than grey, don't you think?).
This tutorial is for a base in any boxed corner bag (and it can be adapted for other bag constructions).
[показать]1. Measure the length of the base seam (above) and then the boxed corner seam (below).
2. Round both measurements down by around 6mm (1/4 inch). For example, on the boxed corner seam below, I'd round down to 6.5cm.

3. Cut a piece of Peltex (it doesn't matter if it's single-sided or double-sided fusible) or heavy weight Fast2Fuse to the (rounded down) dimensions of the base seams. (I find that a rotary cutter and quilting ruler are the businessfor this job).

4. Roughly cut a scrap of fusible woven interfacing large enough to wrap about 2 and a half times around the base piece - folding along the long edge. You'll also need a generous seam allowance (overhanging the Peltex/Fast2Fuse) at each of the short ends. No need to worry about accuracy here, folks!

5. Wrap the interfacing around the base piece and fuse it all together with a hot iron. The interfacing will stiffen as it cools. You can add further layers of interfacing if you'd like to make the base more rigid.
NOTE: If you use double-sided fusible Peltex or Fast2Fuse, you can use calico or fabric scraps instead of interfacing. (That's what I used to do before I discovered the benefits of layering up fusible interfacing).
