I saw your post about the Wrap- N-Mats and your dislike of the plastic smell. I found a solution and thought you might want to share with your readers. I made my own cloth diapers for my dd who is now 2 1/2 and potty trained. I have tons of PUL left over. This is polyurethane laminate coated fabric. After I read your post last night, I decided to wrap my sandwich in it. I made the sandwich last night, refrigerated it overnight and carried it in my insulated lunch bag. My sandwich was nice and soft at lunchtime. It didn't get stiff. I will be making more of these now for my family and my friends.
To get an idea about what the fabric looks like you can go to Diaper Shop. It's fairly soft considering it's coated, especially if the material that was coated is a knit. A little more stiff if it's a woven, but still folds up more like a thick napkin than plastic. I bought lots of "diapercuts" from Diaper Shop. You can get a nice variety of fabric choices this way, without having to buy a full yard. They run about $3 a cut. and could probably get 4 out of one 20x20 cut. Much more affordable than the Wrap-N-Mats.As you can see from Lilia's pictures, making a PUL wrap looks easy, with no layers of fabric and plastic to sew together. And the fabric selection is great, with both fun prints and plain solids. Thanks, Lilia!
