Here are instructions to sew a simple drawstring bag. They are so handy to use for toys, games, and puzzles, or even as gift bags.
First, cut two rectangles of fabric. I used 14" x 15".
With right sides together, sew along three sides of the rectangle.
Next fold down the top edge about 1/4" and press with an iron. Then fold it down again about 3/4" and press again. This will enclose the raw edges along the top.
Now sew along the edge of the fold to make a casing for the drawstring. End your seam about an inch from where you started. This is where the drawstring will be inserted. Make sure that you backstitch when you start and end to secure the seam.
Next cut a length of ribbon that is about 3 times as long as your top edge. Attach a safety pin in one end of the ribbon and insert it through the opening you left in the seam. Inch the safety pin along through the casing until it comes full circle and out the same opening. Remove the safety pin and then tie the ends together securely.
Now if you turn your bag inside out it's done. But, if you want to take a few more minutes you can make it a little better. It isn't that hard to make something called a gusset and it will make the bag wider and more usable. All you do is lay your bag flat and draw a square on each corner of the bottom. The size of the square will depend on the size of your bag, but keep in mind that a 2 inch square will make a 4 inch wide bag. I
used 1 1/2 inches for this bag. After you draw square, cut it out.
This is the trickiest part of the whole project. Pick up the bag and match the side and bottom seams together, squashing the sides so the new seam you are going to make lays flat. Pin it together and sew along the raw edge. Repeat this for the other corner.
That's it! You're done! Now just turn the bag inside out and fill it with stuff! If your fabric is kind of flimsy you may want to iron along the edges just to make it look better, but it's not totally necessary.
Good luck!
