Learn how to sew a DIY drawstring backpack with this easy to follow step by step tutorial. A simple sewing project for beginners since you only need to know a few sewing basics. This lined bag can be made in less than 2 hours!
My three older girls (11, 9 and 7) have been asking for little backpacks to take on field trips and on outings with their friends. I love an opportunity to sew, so I decided to make them some myself!
I designed these bags so that the straps can be adjusted for littler kids or teens. Because I didn’t want any raw edges exposed, I made them fully lined.
This was a fun little project that only took a couple hours to whip up. My girls are thrilled with their new bags, and I know you’re going to love making one too!

To make things as clear as possible, there is a picture of every single step in this tutorial!
what you need to sew a Simple drawstring backpack:
- 1/2 yard of main fabric – cotton fabric for the outside of that backpack.
- 1/2 yard of coordinating fabric – cotton fabric for the lining on the inside of the bag and tabs.
- 4 yards of thick cording, rope or string – to make the backpack straps.
- thread – that matches both of your fabric choices.
- 2 large beads – The beads are to keep the knots in the rope from pulling through the tabs. I used these Wooden Beads for mine.
- sewing machine – I’ve had my Brother sewing machine for 12 years now. It’s really basic and easy for beginners to use.
- seam ripper – you’ll need a simple seam ripper for this project.
- pins – you won’t get very far without a handful of straight pins
- fabric scissors – good quality sharpened fabric scissors.
- iron and ironing board – for pressing seams.
Cutting Directions for one Backpack:
Cut the following pieces of fabric:
- 2 rectangles 15″ x 15″ – out of the outside fabric
- 2 rectangles 15″ wide x 17.5″ – out of the lining fabric
- 1 rectangle 2″ x 6″ – out of the lining fabric
how to sew a Lined drawstring backpack:
Step 1: Prepare the Corners of the Backpack
First, you will need to cut a 1.5″ x 1.5″ square out of each of the bottom corners of each of the 2 lining pieces and each of the 2 outside pieces of fabric. These will become the boxed out bottom corners of the bag.
Step 2: Make Tabs to go at the bottom of the bag
Take the 2″ x 6″ rectangle and iron it in half lengthwise. Open the rectangle up and fold each long side toward the crease you just made. Iron these. Then fold the rectangle in half again lengthwise and iron. You should end up with a 1/2″ x 6″ rectangle. Sew close to the long open edge of this piece. Cut this in half making 2 – 3″ tab pieces.
Fold each of these 3″ pieces in half and pin to the main outside fabric pieces, 1″ above each of the squares you cut out in step 1. Baste these in place.
Step 3: Stitch the Sides and Bottom
With right sides together and matching the cut out corners, sew both pieces of the outside fabric together using a 1/2″ seam allowance down the long sides. Do not sew the cut out corners.
Repeat this step with the lining fabric, but leave a 3″ gap in the middle of the line of stitching along the bottom.
Press the seam allowances open.
Step 4: Box Out the Corners
Now you will need to box out the corners on the lining and outside piece. To do this, pinch the top corner of the cut out squares on the front and back and pulling them apart, line up the side seams and bottom seams. The raw edges of the corner cut out should now be straight across, sew across the corner with a 1/2″ seam allowance.
Step 5: Sew the Lining to the Outside of the Drawstring Backpack
With right sides together, put the outside of the backpack into the lining. Line up the top edge of each piece, making sure seam allowances match up. Stitch them together.
Using the gap you left in the stitching at the bottom edge of the lining, turn the whole bag right side out. Pinch the gap closed with wrong sides together and stitch it closed.
Step 6: Make the Track for the Straps to Go Through
To make a drawstring casing for the straps to go through at the top of the bag, fold 1″ of the lining fabric up so that its visible from the outside of the backpack. Iron this folded edge up and stitch close to the seam between the lining and the outside.
Using a seam ripper, pick out the stitching in the seam allowances on the sides in this track for the straps to go through. This is where you will feed the strings through. To keep the seams from unraveling further stitch and backstitch a few times along the top edge of the bag where you picked the stitching out.
Step 7: Add the drawstring cord/straps
Next, cut your strings or rope for the straps into 2 – 2 yard long pieces. Use a piece of clear tape to go around the ends of the rope to keep them from unraveling while you feed them through the track on the backpack.
Take the first piece of cord and feed it through the track, coming back through the same hole you started it in. Do this same thing with the other cord so that you have two pieces of rope coming out of each side of the backpack.
Put both of the ends of each arm strap through each of the tabs at the bottom of the backpack and feed them through a wooden bead on each side.
At this point its best to try the backpack on your child to see how long the straps should be before you knot them and cut them.
When you have both sides how you want them and they look even, tie a tight knot under each bead and cut the ropes off underneath.
