Baby Clothes Quilt: How Many Pieces, and How to Make One

A baby clothes quilt is a memory quilt sewn from a child's outgrown onesies, sleepers, and little outfits, usually cut into small 6-inch squares. At that size, with 2-inch sashing, a crib-size quilt about 38 by 54 inches takes 35 panels, which is roughly 18 to 35 pieces of clothing, and a throw takes 72 panels. Most baby clothes are knits, so each piece gets lightweight fusible interfacing on the back before it is cut. Keep snaps and zippers out of the seams, save the sweetest details, like an embroidered name or a tiny pocket, for the middle of a panel, and let one calm sashing color pull all those prints together.

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 baby clothes (onesies, sleepers), a cutting chart, and yardage. It holds up to 48 pieces, which is enough to plan a crib-size quilt of 6-inch panels and to try out your layout before you cut. For a bigger quilt, plan it in two halves.

How many do you need?

These counts use 6″ × 6″ finished panels (where the designer starts for baby clothes (onesies, sleepers)) 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.

Queen16812 across, 14 down94″ × 110″84 to 168

A onesie front usually gives one 6-inch panel, and a sleeper or a toddler shirt often gives two, so the count is a range. Gather a few extra; the ones you don't use go back in the keepsake box.

How to make a baby clothes quilt

  1. 1Gather and wash. Collect more pieces than you think you need, then wash them without fabric softener, which can keep fusible interfacing from sticking. Take a photo of each one before you cut. It takes the worry out of the scissors.
  2. 2Open each piece flat. Cut along the side and shoulder seams so you are working with one layer. Snip off snaps, zippers, and tags anywhere they would land in a seam.
  3. 3Stabilize the knits. Fuse lightweight fusible interfacing to the wrong side of every knit piece, cut about an inch bigger than your panel. Fuse first, then trim. Knits sewn without it stretch into waves.
  4. 4Cut the panels. For 6-inch finished panels, cut 6½-inch squares, which leaves a ¼-inch seam allowance on every side. Center the design, an embroidered name, or a little pocket in your square ruler before you cut.
  5. 5Sew the rows. Lay the panels out, then sew each row with sashing strips between the panels. Join the rows with long sashing strips and press toward the sashing.
  6. 6Quilt, bind, and label. Layer it with batting and backing, quilt it, and bind it. Add a label with the child's name, the years the clothes cover, and who made it.

A few things that make baby clothes easier

  • Sort by color before you plan. A box of pastels and a box of brights each make a happy quilt; one of each can fight.
  • Cut the pieces you love least first, so your hands are warmed up before you get to the coming-home outfit.
  • Ribbed cuffs and necklines are very stretchy. Leave them out, or use them only on a small piece that is fully fused.
  • Mixing in T-shirts or a parent's shirt? The designer lets each piece be its own kind and size.

Frequently asked questions

How many onesies do I need for a baby clothes quilt?

With 6-inch panels and 2-inch sashing, a crib quilt about 38 by 54 inches takes 35 panels, which is 18 to 35 pieces of clothing. A throw about 62 by 70 inches takes 72 panels, or 36 to 72 pieces. A onesie usually gives one panel and a sleeper often gives two, so the range depends on what is in the box.

What size squares should I cut for a baby clothes quilt?

Six inches finished (cut 6½ inches) is a good starting size, because it fits the front of most onesies. Go down to 4 or 5 inches for the tiniest pieces, and up to 8 inches for toddler shirts and bigger prints. You can mix sizes; the designer keeps the rows straight with background spacers.

Do baby clothes need interfacing before quilting?

The knits do. Onesies, sleepers, and little T-shirts stretch, so fuse lightweight fusible interfacing to the back of each one before cutting. Woven pieces, like a tiny button-down, overalls, or a cotton dress, usually don't need it.

What do I do with pieces too small for a full panel?

Give them their own small size and turn on "Group small pieces" in the designer. It stacks the little ones into a block about as tall as your bigger panels, so a sock-sized piece doesn't have to be stretched to fit a 6-inch row.

Can I keep the snaps, buttons, and appliques?

Appliques and embroidery can stay right in the middle of a panel; quilt around them. Take off snaps and buttons that fall in a seam allowance. If the quilt is meant for a little one to use, take off anything hard that a small child could pull loose.

Is a baby clothes quilt safe to put in a crib?

The American Academy of Pediatrics recommends keeping blankets, quilts, and other soft bedding out of a baby's sleep space for the first year. A baby clothes quilt is lovely as a wall hanging, a keepsake, or a supervised play mat, and as a toddler or big-kid quilt later on.
