Step 1: Materials
2 packages of doublefold bias tape
matching or contrasting thread
plastic shopping bag & large piece of paper (for making pattern)
scissors, pins, sewing machine, iron
Step 2: Making the pattern
Draw 2 lines an inch apart at the bottom of your paper.
Line the bottom of the plastic bag up with the top line. You will need the inch below for seam allowance. Make marks at the top of the bag opening and the sides of the handles.
Remove the plastic bag and draw straight lines for the handles. Lay the pillowcase on top of your pattern, to make sure you make the pattern as wide as the pillowcase. Fold the paper in half. Draw curves at the bottom of the handles on both sides. Cut the pattern along those lines and unfold. I extended the length of the straps, but you can make them shorter if you like.
Step 3: Pin and cut
Step 4: Apply the binding
Step 5: Sew the straps
Turn the bag inside out and with RIGHT SIDES together, sew across the bottom of the bag and the tops of the straps again, using a 5/8" seam allowance. The bag will look kind of strange at this point. This will create a "French Seam. It is very strong, and all the raw edges will be encased in this seam. Turn the bag right side out, and enjoy your shopper!
