So it drives me crazy to use and throw away ziplock baggies. I decided to make some of my own using a series of various tutorials I've seen over the years I threw a few together using a tablecloth and velcro.
I cut rectangles from the tablecloth (a few of the tutorials I've seen have used the inside of plastic cereal bags etc for the inside layer, but I decided to use the wipeable table cloth for both sides.
I sewed up three sides face to face.
I turned it right side out.
I folded the last side in, and sewed a line.
I added some velcro to the part I folded up and sewed it to make a pocket (easier than doing it afterwards).
Folded it up leave a flap, and sewed up both sides.
