Becky, Im in Ireland and can buy it in my local fabric store and also in a local store that sells household "stuff" like bed linen and cutlery! Im sure someone will post where you can buy it in the US soon

Hi Becky I posted the yellow bag with the plastic window & I recently bought pillow cases from the dollar store & they came in a plastic type bag & this is what I used!It is thinner & works well! Anyway that's what I used! recycle too!

Becky, most fabric shops carry clear plastic in different thicknesses. I got mine from Hancock Fabrics. They also have clear plastics with the cutest flipflops, smileys, strawberry shortcake little girl, etc. I got a few pieces to make beach tote bags for my grand kids.

Just as question....had anyone tried the plastic from a shower curtain? I was wondering if it was just as good AND a cost saver...if not, then I won't even attempt. Just thought I'd ask since I too want to try a peek-a-boo bag.

if you go to http://www.smartneedle.com/clearvinyl.html they sell the clear vinyl in packages. I have used it for alot of projects and I love it. I believe it is 5.99 for 12 sheets of high quality. I highly recommend it. If you are going to do all that work for a project then I would recommend using this.

Your local hardware-Walmart probably has Clear plastic in a roll of different thickness (Table cloth Covers).Home depot -Lowes sell drop cloths different gauge thickness also.

I just got mine at the Joann - regularly 5.99 a yard - but it is like 60" wide so you get quite a bit. I went with the thickest clear one they had - I want it for little bags that are clear on the front (ITH from MooseBStitchin). They call it Vinyl there and it is on big rolls in the home decor section.
