Jean Quilt: How Many Pairs of Jeans, and How to Cut Them

A jean quilt is a quilt made from old blue jeans, cut into squares and sewn into a sturdy, heavy quilt that is a favorite for picnics, camping, and the back of the truck. With 10-inch squares and 2-inch sashing, a throw about 58 by 70 inches takes 30 squares, which is about 8 to 15 pairs of adult jeans, because each pair gives 2 to 4 squares from the upper legs. Regular denim doesn't stretch, so it needs no stabilizer, but it does need a jeans needle and seams pressed open. Mixing light, medium, and dark washes is what makes a jean quilt look like patchwork instead of one big blue square.

Plan yours free in the Memory Quilt Designer

Photograph each piece, and the designer packs them into balanced rows and prints the pattern with prep for jeans or denim, a cutting chart, and yardage. It holds up to 48 pieces, enough for a throw or a twin at 10-inch squares, and a back pocket can go in as a piece of its own.

Plan a jean quilt

How many do you need?

These counts use 10″ × 10″ finished panels (where the designer starts for jeans or denim) with 2″ sashing between them, laid out by the same math the designer uses. Finished sizes are before any border. The designer itself plans up to 48 pieces and quilts up to 96 inches wide, so for the largest sizes here, plan the quilt in two halves.

A pair of adult jeans usually gives 2 to 4 ten-inch squares from the upper legs, front and back. Wide-leg and bigger sizes give more; skinny, slim, and kids' jeans give fewer, so lay a 10½-inch ruler on a leg before you count.

How to make a quilt from old jeans

  1. 1Wash the jeans. Wash and dry them first. Dark, new denim can bleed blue dye, and washing now means it won't bleed into the sashing later.
  2. 2Cut the legs open. Cut each leg off just below the back pockets, then cut it open right beside the thick outside seam, not through it. Each leg lies flat as one long piece.
  3. 3Save the pockets. Back pockets make wonderful panels. Cut the panel around the pocket and leave the pocket working, but keep rivets and belt loops out of the seam allowances.
  4. 4Cut the panels. For 10-inch finished panels, cut 10½-inch squares from the widest part of each leg. Mixing light, medium, and dark washes gives the quilt its patchwork look.
  5. 5Sew with a jeans needle. Use a jeans or denim needle, a slightly longer stitch, and a walking foot if you have one. Press each seam open to spread out the bulk.
  6. 6Finish it. Denim is heavy, so a thin batting, or none at all, keeps the quilt from getting too weighty. Straight-line quilting is easiest through denim. Bind it, and label it.

Another way: the denim rag quilt

If you want the easiest denim quilt there is, make it rag style. Each square is sewn with its seams on the front, then the seam allowances are snipped and washed until they fray soft. There is no binding to wrestle through all that denim. The rag quilt calculator works out the squares and yardage for that style.

Frequently asked questions

How many pairs of jeans do I need for a quilt?

With 10-inch squares and 2-inch sashing, a crib or lap quilt about 46 by 58 inches takes 20 squares, which is 5 to 10 pairs of adult jeans. A throw about 58 by 70 inches takes 30 squares (8 to 15 pairs), and a twin takes 48 squares (12 to 24 pairs). Wide legs give more squares than skinny jeans.

What size squares should I cut from jeans?

Ten inches finished (cut 10½) fits the upper leg of most adult jeans. Kids' jeans and skinny styles are narrower, so use 6- or 8-inch squares for those. Lay your square ruler on a leg before you decide.

Does a denim quilt need batting?

Not always. Denim is heavy on its own, so many quilters use a thin batting or skip it and back the quilt with flannel. That keeps a picnic or camp quilt warm without making it too heavy to fold.

What needle do I use for sewing denim?

A jeans or denim needle, which has a stronger shaft and a sharp point for heavy woven fabric. Lengthen the stitch a little, sew slowly over thick spots, and keep the flat-felled jean seams out of your seam allowances.

Does denim need interfacing in a quilt?

Regular denim doesn't stretch much, so it doesn't need stabilizer. Stretch denim, the kind with spandex in it, holds its shape better with lightweight fusible interfacing on the back.

Can I mix jeans with T-shirts or flannel?

Yes, but the weights are very different. Stabilize the T-shirts, and think about putting the denim in its own rows or around the border so the heavy seams don't pull the lighter panels. The designer gives prep for each kind you use.
