I recycle my large plastic jugs- yes,! Clorox jugs for a bottom in a purse? believe it or not, you can press the plastic flat with a Warm iron between several sheets of tissue, I also use it to make plastic letters, etc. - its real easy to cut to size,lay something heavy (a book) for a couple of minutes (while still warm) to keep it flat and you have free craft supplies.

I use plastic canvas ans template plastic as it is washable and remains stiff.

I got scraps of corrugated sign material at a sign shop. easy to cut with rotary cutter or Xacto, and cheaper than the Bag-e-bottoms from Lazy girl. (Sometimes the shop will give you the smaller scraps) Just have to be sure to round the edge a bit so it won't poke a hole in the fabric.

I used several pieces of heavy plastic canvas. It can be left in when washing. I also found something the other day that I am going to use for stencils and templates and it would also be great for the purse bottoms. It is a package of flexible cutting mats from the kitchen department at Wal Mart. There were 3 to the package. It can be cut with scissors and is white. The sheets are 12 x 15 and only cost about $5.

I use Peltex which is an ultra, super stiff fusible interfacing. You can buy it at JoAnn's. I cut 2 pieces to the size I need and iron or fuse them together. It's then very stiff after it cools from the iron. Next, I sew it to re-enforce it in small triangles starting at one end of my piece sewing up on an angle and when you get to the end, you pivot the fabric and go back down to finish up the triangle. I try to get 3 or 4 triangles across my piece. Once again, doing the stitching re-enforces the Peltex. Then depending on the purse I'm making, I try to sew it directly into the "inside" (beteen the layers of fabric and the batting) of the bottom of the purse and then sew it down around the edges of the bottom of the bag as opposed to "sleeving it". The sleeves work, but as someone else mentioned, they do shift around in your bag a lot and stuff does in deed fall underneath. But my long arm quilting lady told me about this and it works beautifully. Only one problem, peltex is not cheap, but best to buy it at Joann's when they either run their 50% off on interfacings, or those of you who were lucky enough to get the 60% off coupons could stock up on it if you make a lot of purses.

I like to use corrugated plastic signs from home depo or old political signs recycle them. No one will ever know.
I lucked out at a yard sale and got a big box of them from some one who went out of business "I buy houses "

Most frame shops will give you their scraps of matting board, which make great purse bottoms. Cut them for a tight fit in the bottom of the purse, and just insert them into a facric cover.
