1.Cut your fabrics and vinyl.
*two pieces outside fabric 22x22 inches (I used heavier weight canvas.)
*two pieces interior fabric 22x22
*two pieces vinyl 22x22
*two pocket pieces (mine are half moon shapes-5 inches across at the top and 6" deep)
*one half moon shape vinyl for pocket-same size as pocket pieces.
2. Purchase (or make) extra wide double fold bias tape. I used almost all of one package of Wrights Bias Tape. Find it at Joanns or Hobby Lobby. If you decide to make it yourself, go ahead and pre-make 3 yards worth.
3. Purchase two pieces of 77 inch long webbing--I always use heavy duty cotton webbing, as I find the polyester webbing can be thinner and cheaper feeling. (Total - 140 inches or almost 4 yards).
4. Find the sewing machine's teflon (NONSTICK) foot, a pair of heavy duty scissors, and matching threads.
Use clamps or clothes pins to hold the vinyl to the fabric without piercing it with sewing needles. Needle holes don't disappear on vinyl, be mindful of this. Sometimes I don't care and use needles anyway--but just a word of warning first. :o)
Here we go.
1. Clamp your vinyl piece to a outside fabric piece and sew it on. Do this for both outside fabric pieces.
Don't forget to change your sewing foot--it will help SO much when dealing with vinyl.
Now sew on the webbing. I cut two pieces of 70 inch webbing. (Measure against your own body to confirm proper placement.)
Measure four inches in from the left side, four inches in from the right side. These are the measurement lines the webbing should line up with to be centered. (Make a tiny mark with a marker, covering it up as you sew on the webbing.)
Line up the end of one piece at the very bottom of the bag side you're working with. Pin in place, and sew. Be mindful the webbing is not twisting in any way. The webbing ends must be to the very bottom of the bag pieces. (See pictures.)
Now you will have two pieces shaped like this:
Pin them right sides together and sew along the curved edge. Leave the top open for flipping right side out.
Flip right side out again:
Place Vinyl piece on top of pocket, the side that's facing OUT. Pin bias tape over this, carefully, around the curved edge. Hold in place with clamps while sewing.
(Yes friends, I took this picture before placing the vinyl on..oops!)
Place the two outside pieces of the bag RIGHT sides together and clamp or pin in place. We are sewing the side seams here, as well as a bottom seam.
Be sure you have the top--at the top.
Sew down each side and across the bottom. Use 1/2 seams at a minimum. It's probably a good idea to double stitch these seams if this bag is going to carry books or heavier items.
Now for the boxing. (ugh-difficult to explain, but I'll try!)
Pinch in 2 inches from the bottom and side seams on one end. Pin, then mark. Sew this several times for a strong corner bottom end. Do the same with the other side.
Confused? Look at these close-ups:
After sewing this, trim off the excess.
Repeat this step for other box corner. We will visit this step again for the interior of the bag.
Grab the two pieces of interior fabrics and pin them right sides together. Sew down each side and across the bottom.
Fold down one inch on the top portion and press.
Make the boxed corners just as we did for the exterior part. Measure in two inches, mark,sew,cut.
