My sister saw some cloth snack baggies on pinterest and asked if I could make them. She even sent a tutorial. I did look at it at the time, but it was essentially: make bag, add velcro, so I didn't go back to it. The tutorial called for a lined bag (neater look inside) but I read a few "mom blogs" that mentioned the crumbs work their way between the bag, so they don't like them lined- so I made two that are unlined (serged edges inside).
I'll send these down to my sister and see which style she likes and, if she wants, make a bundle more. I'm suspecting with twins the snack baggies go fast- and it sounds like she is trying to reduce plastic use.
Hopefully she'll go for the unlined option- as it takes only a few minutes to make. These bags are practically free, as they just use scraps- only need to purchase velcro!
