This is by far the simplest bag pattern I have used. Years back I had a re-usable bag someone had given me. It fit two 1 gallon jugs of milk in it perfectly. When I gave it a good look-sie I was surprised to see how easy it would be to make my own bags.
1 yd of Fabric- (in this demo I used oil cloth)
Ribbon (go nuts- make your bag fancy)
cardboard (to make the pattern)
Step 1: Cutting Out the Pieces
I like to cut my pattern out of cardboard for this project. You can make the pattern just as easily from fabric.
There are two pieces:
1) the main body- a large rectangle that is 36"x16"
2) the sides- a smaller rectangle that is 7"x16"
*on piece #2 at one end of the width curve the corners.
Now that you have the patterns, use them on your fabric and cut it out.
Note that with piece #2 you need to cut 2 of these out.
If you want to get fancy cut piece #1 from one fabric and #2 from a different design of fabric.
