Here's what I did!
Fabric ( I just measured my bag plus a little, so it depends on what size zipper bag your using)
Sewing Supplies ( Machine, Thread, Etc)
To measure my fabric, I just placed my bag on top and gave myself some room on each side.
Prepare your plastic bag, cut a straight line down the side removing the excess of the zipper that was thick.
See how the end looks different? You want to get rid of that so that your bag turns right side out better...
Open up your bag, like this... Just wiggle the plastic "toggle" off and save.
Fold over the short side ( top) of your fabric, and pin it to fabric making a nice clean edge on the outside of the bag. Sew. REMEMBER you are going to put the toggle back onto the bag, so leave plenty of room for it to move freely above the fabric. ( See how the "toggle" is still on the bag? Thats so I could measure where to sew)
Reattach your "toggle" Just slide it back on. I zipped it open and close a couple times to make sure it worked. Then flip bag inside out, I zipped it half closed and then flipped.
Turn your bag inside out and sew the two side seams, making sure you get both the bag and fabric. Trim off excess.
Flip right side out and your done! Now, your lunch bags look great, and you feel guilty about throwing them out! So your being *green* and saving the enviroment all while being cute!
