Preparing The Fabric
Preparing the fabric is an important part of sewing a square bottom drawstring bag. Good preparation helps the fabric stay neat and easy to sew.
Take your time to measure, cut, and mark the fabric carefully. This makes the sewing process smoother and your bag look better.
Measuring And Cutting
First, measure the fabric pieces you need for your bag. Use a ruler or measuring tape for accuracy. Make sure your measurements match the size you want for the bag.
After measuring, cut the fabric with sharp scissors or a rotary cutter. Cut slowly to keep the edges straight and clean.
- Measure twice before cutting
- Use a flat surface for cutting
- Keep the fabric smooth and wrinkle-free
- Cut all pieces needed for the bag
Marking Seam Allowances
Mark the seam allowances on your fabric before sewing. Seam allowances are the extra fabric edges used to sew pieces together. Usually, a 1/2 inch allowance works well.
Use a fabric marker, chalk, or pencil to draw the seam lines. This helps you sew straight and keep the bag’s shape.
- Mark all edges where you will sew
- Use light, easy-to-remove marks
- Check that marks are clear and visible
- Keep marks inside the seam allowance area
Sewing The Main Body
Sewing the main body is the first step in making a square bottom drawstring bag. It forms the bag’s basic shape.
You will join fabric pieces and prepare the bottom to give the bag depth and strength.
Joining The Sides
Place the two main fabric pieces right sides together. Align the edges carefully.
Sew along both side edges with a straight stitch. Leave the top open for the drawstring.
- Use a ½ inch seam allowance
- Backstitch at the start and end for strength
- Press seams open or to one side
Creating The Square Bottom
To create a square bottom, pinch the bottom corners of the bag. Match the side seam with the bottom seam.
Sew across the corner about 1½ to 2 inches from the tip. This will form a flat bottom.
- Measure the same distance on both corners
- Trim the excess fabric after sewing
- Press the corners flat to shape the bottom

Making The Drawstring Casing
Creating the drawstring casing is an important step for your square bottom drawstring bag. This casing holds the string that closes the bag securely. Follow these simple instructions to make a neat and strong casing.
Start by preparing the top edge of your bag fabric. You will fold and sew the fabric to form a tube through which the drawstring will pass.
Folding And Pinning
Fold the top edge of the fabric down to create the casing. Measure carefully to ensure the casing is wide enough for your drawstring. Pin the folded fabric in place to keep it from moving while you sew.
- Fold the fabric down about 1 inch (2.5 cm).
- Pin the fold evenly along the entire top edge.
- Make sure the pins are parallel to the edge for easy sewing.
- Check that the fold is straight and smooth.
Sewing The Casing
Use a sewing machine to stitch the casing. Sew close to the bottom edge of the fold. Leave a small opening for threading the drawstring later. Backstitch at the start and end to secure the stitches.
| Action | Details |
| Stitch length | Medium (2.5 to 3 mm) |
| Seam allowance | 1/4 inch (0.6 cm) from fold edge |
| Opening size | About 2 inches (5 cm) |
| Thread type | Strong polyester thread |
Inserting The Drawstring
Adding a drawstring is the final step in making your square bottom bag functional. This guide helps you pick the right material and thread it properly.
The drawstring should be easy to pull and strong enough to hold the bag closed securely.
Choosing The Drawstring Material
Select a material that fits your bag style and use. Cotton cords, nylon ropes, and satin ribbons are common choices.
- Cotton cords:Soft and natural, good for casual bags.
- Nylon ropes:Durable and smooth, ideal for outdoor use.
- Satin ribbons:Decorative and shiny, perfect for gift bags.
- Leather strips:Strong and stylish, best for heavy bags.
Threading The Drawstring
Threading the drawstring requires patience to get it through the casing smoothly. You can use simple tools to help.
| Tool | Use |
|---|---|
| Safety pin | Attach to drawstring end to guide through casing |
| Bodkin | Special tool for pulling cords through narrow channels |
| Paperclip | Unfold and use as a needle for threading |
Once the drawstring is through, even out both ends. Knot the ends to stop fraying and keep the string from slipping out.

Let’s focus on securing the drawstring ends and explore optional embellishments to enhance your bag’s appearance.
Securing Drawstring Ends
