Baby Sleep Sack

Does your little one move nonstop—even while sleeping—and keep kicking off the covers? With this tutorial, you’ll both rest easier: baby sleep sack to the rescue!

Baby Sleep Sack

Video class

This video is for members

Join Lulu Ferris to watch the complete class and sew along at your own pace.

What you’ll make

Sew a warm baby sleep sack that stays in place as a little one wiggles and changes position. A long zipper opens the sack, while buttons or snaps fasten the shoulder tabs.

The sack combines an exterior, batting, and lining. The class demonstrates versions made with one main fabric and with two fabrics for a contrasting look.

What you’ll learn in this class

  • Arrange the exterior fabric, batting, and lining.
  • Insert the zipper and handle its slider around tricky areas.
  • Use a zipper foot and a walking foot where appropriate.
  • Trim or clip curves for smoother turned edges.
  • Turn the sack through an opening in the lining.
  • Close the lining by machine or with the invisible stitch.
  • Add buttons or snaps to the shoulder tabs.

Practice zipper insertion further with the weekend bag tutorial.

Fabric and notions

You’ll need exterior fabric, batting, and lining fabric. The demonstrated sack pairs a printed exterior with a plain white lining.

Choose a standard or invisible zipper. Large buttons or snaps fasten the shoulder tabs.

Make it your own

  • Use one exterior fabric for a unified look.
  • Combine two fabrics for contrast.
  • Choose a standard or invisible zipper.
  • Finish the shoulders with large buttons or snaps.

Pattern sizing

The downloadable pattern includes three baby and toddler sizes. The class sample uses the middle size.

The video comes with a downloadable A4 pattern containing separate front and back pieces for the exterior, batting, and lining.
