I use this all of the time, but I get mine at a business that makes signs, and it costs $2 for a large sheet that I can get 4-5 purse bottoms out of. And last time I went in, she gave me a scrap piece about the same size that they had left over from a job that was perfect, and didn't charge me a cent. This stuff holds up forever! I make a sleeve for it out of my lining fabric, and just slip it off when I wash my purse.

Yes, those signs are made of corroplast - corrugated plactic - sheeting. I use it and foamcore for lots of different things.

I also use foam board for bag bottoms. I have also used a couple of left over pieces of plastic canvas.

Well, I need to get out more often! I had not a clue what people were talking about with the "vote" signs :):) All I knew at the time was I needed 2 large (10" x 21" ) pieces of something and refused to pay $$$ for plexi glass. I guess you ladies are just really good recyclers also! My eyes are slowly being opened... :):)

Maybe when its election time again and all the signs come up missing ......

I really like that idea. You can also use cardboard like the cereal boxes. I do like your idea better than cereal boxes.

It was $24 for what I needed-too expensive, so I started cruzing the isles for something. I found "Plastic Cardboard"! It is the "for sale" signs - not the solid thinner, flexible, plastic but literally looks like white plastic cardboard. I used the rotary cutter (I know, it was an old blade though:) ) and used extra pressure to cut it. I covered it with fabric and if it is soiled, it can easily be cleaned. It only cost $6 for what I needed. And did I mention it is very lightweight!

I can make a fairly substancial bottom by ironing craft backing to a couple layers of fabric. I try to cut it so that there's an "unbacked" border around the bottom pieces. The craft backing is pretty stiff, so a few thicknesses get to be hard to sew thru

I love using the coroplast in the bottoms of my bags. It's also what I wrap my fabric around to arrange my stash.
The best part of using it in bags is it tolerates water, so if the bag accidently gets wet, the bottom doesn't fall apart. It also is a good foundation if you like to add "feet" to the bag.
I used this to make temporary gates in my house for puppy training too, but that's another story.

My daughter uses plastic canvas in the bottom of the bags she makes. Slip them inside a fabric case and if you have something leak or spill you can easily clean the bag and reuse the plastic canvas. She got a super deal on the canvas on clearance at WM.
