In this tutorial we will be making the body of the bag. Once again, you can find the dimensions for the varous sizes under the Stats tab above. I am making a medium sized bag. Fold the largest piece of fabric in half. Fold the two smallest pieces of fabric in half lengthwise. If you prefer not to crease the fabric you can use your ruler to find the center of all three pieces and mark with a pen.
You will need small pieces of tape to attach the sides to the bag. Cut a piece of matching tape to 3" long. Cut that in half lengthwise, leaving you with 2 3'x1" pieces of tape.
Line up the creases of the fabric pieces. Leaving a very small gap of perhaps 1/16" of an inch, attach the smaller piece to the large piece with one of your pieces of tape.
Do that on both sides.
Once again we will be using pieces of tape cut in half lengthwise to secure the sides to the bag body. Lay a piece of tape on your board that is the same length as your side pieces. Cut that in half. Lay those pieces half on/half off the side pieces.
Now we will attach the side pieces to the bag body. Fold the sticky edge of the piece you just attached in half lengthwise so the sticky is facing you.
Bring the large side of the bag up to meet that edge and secure. NOTE - this can be a bit tricky. It is easier if you have someone help you with this step. Bring both sides up and attach them to the sticky edges of the tape. This is creating a seal with no exposed sticky on the inside.
We wil be reinforcing every seam with tape on the outside as well. For this we will use full sized pieces of tape. Cut four pieces of tape to the length of your side pieces.
Use those pieces to cover the outside seams.
Use a small piece of tape to reinforce the bottom seams as well.
All done with the body of the bag. Stay tuned for Part 3 where we will add the flap and the strap.
