Make 14 pieces of fused plastic. Here's the how-to video.

Cut 8 squares that are 7 x 7-inches.



Cut 6 rectangles that are 5 x 7-inches.



There's no real right or wrong sides to your plastic. It all depends on what you want to be seen on the outside of your bag.

Next you are going to stitch two squares, right sides together, along one side using all-purpose thread with 1/2-inch seam allowances. Use a moderately long stitch length or you will perforate the plastic. Repeat for the remaining pairs of squares.



Pair the rectangles and stitch one of the short sides of each pair together.

Finger press the seams open.



Stitch all of the seams open, 1/4-inch from the seam.

Next, place two sets of the stitched squares, right sides together. Since you can't pin the plastic without creating small holes, it's handy to use paperclips to hold the pieces together so they don't slide.



Just be careful to remove the clips before you stitch over them so you don't damage your sewing machine.

Again, finger press the seams open and stitch them down 1/4-inch from the seams.

Finger press one edge of each of the square pieces down 1/2 inch and stitch 1/4-inch from the fold.



Repeat along the short edge of two of the rectangle pieces.



The folded down edges will be the opening of your tote.

Position your straps so they are 6 inches apart and centered on the top edge of each of the square pieces.



You can hold down the straps with paper clips, again being careful not to sew over the paper clips.

Stitch the straps in place.

Lay out the pieces of your tote as shown.



Stitch all four sides to the bottom piece, right sides together.



You can finger press the seams open and stitch them 1/4-inch from the seams as before if you choose.
