Step 1: Materials
- Some sort of fabric (I used an old shirt the first time I did this)
- Needle and thread
- Safety Pin
- A Drawstring/Ribbon (I used the handle from a shopping bag)
- A Ruler/measuring device
- A pen/pencil that will write easily on fabric
- Markers and whatnot for decorating.
Step 2: Measure, Cut, and Mark
Measure out a rectangle with side lengths of (width+1cm) x [(2*height) + (4cm)]
In this case my rectangle was 11cm wide x 30cm high.
The additional bit of fabric is there for seams and for making the lip that the string will pass through (you might not need to add 4cm depending on the thickness of your drawstring, but for me this worked). Also, if you want a wider bottom on the finished product, you'll want to add a few more cm to the height.
Now cut out the rectangle carefully.
Once you've cut out the rectangle, place your drawstring at the top of the fabric and fold the fabric over it to make the lip. Mark how far down the fabric has to go so you know where to stop sewing the sides.
Step 3: Start Sewing
You'll want to sew up the sides to the place you marked (for the lip). Remember, you're sewing up the inside of the bag! I used fabric that was the same colour on both sides, but if you use something that has two different colours, make sure you're sewing the part that will be inside the bag.
