Hard Bottom Inserts

[sugarpouf]

I'm really cheap.  I use those grid-type plastic sheets that are for needlepoint.  You can buy the sheets for like 10 cents each.  I just cut to size, which is especially easy because of the built in grid!

Corrugated plastic can be purchased at Blick's http://www.dickblick.com/zz132/00/ and it cuts like butter.

I first create the exterior, then I use spray adhesive on the insert (corrugated plastic) to adhere to the bottom. Then the interior lining can be attached. The plastic is not only adhered to the fabric itself, but is also sandwiched between the exterior and interior fabrics.

I made a messenger bag for my partner and used part of an old flexible chopping board (cut to size). They're approx. A3 size and I can get a pack of 4 at the bargain store for $2. I actually made a pocket for it so that it is removable. The craftster post -> http://www.craftster.org/forum/index.php?topic=409696.0

Thin disposable cutting boards when they're 'used' up.
