It’s medium size makes it great for kids and grown-ups. The beach towel easily folds up into the backpack, which can hold other items too like a water bottle, goggles, or snacks.

The top of the beach towel backpack has a cotton fabric flap with a velcro closure to keep your items safe. You can even add an inside zippered pocket to keep keys or cash secure (not shown, but I’ll tell you when you could do that using my welt zipper pocket tutorial).

The great size of this beach bag (approximately 17’’ tall x 15’’ wide) makes it easy for kids to carry – but still comfortable for teenagers or adults. There’s also a handy loop for hanging on a peg while you’re waiting for beach day.

It’s the perfect gift for anyone on your list!

Note: This design works best if you like the way the towel looks on both sides, because the back (wrong side) of the towel is what shows on the outside of the backpack.


Back of the towel.

That’s because the cotton backpack piece is sewn to the back of the towel.


Front of the towel.

From the front of the towel, you can barely tell that there is a fabric backpack sewn to the other side. Of course, if you prefer that only the front (right side) of the towel is showing when the backpack is worn, then you can sew the cotton fabric backpack piece to the front (right side) of the towel instead.

Are you ready to sew it?

  • Pin the top ends of the strap to the top edge, 3’’ away from each top corner

5. Place one of the flap pieces on top, right side down as seen above. Pin. This is the backpack exterior.

Pin the remaining 18’’ x 16’’ rectangle and flap piece together also. This is the backpack lining.

Tip: If you would like a hidden zippered pocket inside the backpack, sew a welt zipper pocket to the backpack lining piece now using my welt zipper pocket tutorial.

6. Place the backpack exterior and lining pieces right sides together with the straps and hanging loop sandwiched in between. Pin all the way around, making sure that the straps are tucked inside and don’t get caught in the pins. The seams between the rectangles and flaps should be lined up.

Before removing this piece from the sewing machine, topstitch around the flap 1/4’’ from the edge.

Attach the Hook and Loop Tape (Velcro)

1. Place the cotton backpack piece on your work area with the lining side up (the side without the straps). Pin one side of the 4’’ length of hook and loop tape to the center of the curved edge on the flap, 1/2’’ away from the topstitched edge.

2. Sew around the edges of the hook and loop tape to secure it. Make sure that your bobbin thread matches the fabric on the front of the flap.

3. Place the beach towel on your work space with the back (wrong side) facing up. find the center of one short end. It doesn’t matter which end.

Pin the second half of the hook and loop tape to the back side of the beach towel, centered and 4 1/2’’ below the top edge of the towel.

4. Sew around the edges of the hook and loop tape to secure it.

Sew Together the Backpack Piece and the Towel

1. Place the towel on your workspace with the back side (and velcro piece) facing up. Center the fabric backpack piece on top as follows:

  • The exterior of the backpack piece should be face down with the straps against the back of the towel.

  • The velcro piece on the towel is facing up against the straps on the backpack.

  • Center the backpack on the towel so that there is an equal amount of towel showing on either side.

  • The seam between the backpack and the flap should be lined up with the top edge of the towel.

2. Pin around the 3 sides of the backpack piece – not including the flap. Use lots of pins!

3. Sew around the three sides of the backpack, sewing slowly and removing the pins as you go.

Tip: Using a walking foot (or even feed foot) may help sewing through these thick layers. Make sure to backstitch at the top edges of the towel.

Watch the short video on this page showing how to fold up the towel inside the backpack. If it doesn’t play automatically, you can watch it on my YouTube channel here.

After you make beach towel backpacks for all the kids you know, make Pool Chair Covers with Pockets for yourself and a friend.
