Bum Bags have finally come back in style and I am here for it. I’ve always been a fanny pack fan because of the practical use at concerts, amusement parks, and everyday use for holding all the important things. Of course this trend has hit our yarn community as well and I hope you enjoy this basic granny square version of the bum bag crochet pattern!

Basic Granny Square Bum Bag Crochet Pattern

Change color after every round, or use same color for whole square.

Make a magic circle (If you don’t know how, you can simply do a CH 4 and SLST to the first chain instead)

Round 1: CH 2 (does not count as first stitch). *HDC 3, CH 2* Repeat 3 times. SLST to the first HDC of the round. (12 HDC, 4 CHSP)

Round 2: Sl ST to next CHSP, CH 2, *[3 HDC, CH 2, 3 HDC, CH 1]* Repeat around in each CHSP. (21 HDC, 8CHSP)

Refer to the graphics below to see how to seam your squares together. You can use Slip stitches or simply use a yarn needle and mattress stitch your squares together.

Once the bag is seamed together, make 2 rows of HDC along top opening of the bag, making sure to HDC, CH 2, HDC in the corners of the bag.


For added security for placing items in your bag, I suggest doing SC’s along the tops of the side triangles. View the graphic below for clarification.


I purchased my strap off of amazon you can find it here

Otherwise if you search crossbody bag straps you can find tons of cute options!

If you want to make your own strap, follow the instructions below:

Attach on corner, HDC 3 in CHSP, CH1 and turn.

HDC 2 in first st, HDC, HDC 2 in last st. CH 1 and turn.

HDC across, CH 1 and turn.

Repeat for desired length. End with last row HDC2TOG, HDC, HDC2TOG. Sew last 3 stitch to the CHSP on other end of bag.

Tie off and weave in ends. Your Granny Bum Bag is now complete!
