Cute DIY Onesie for Babies

Fabric: Little Safari Flannel 2 collection from Robert Kaufman

Decorate a onesie for a baby shower gift! It's so easy, and so cute.


  • Plain baby onesie 
  • Cute flannel or knit fabric (We chose the Little Safari 2 collection from Robert Kaufman, which had animal shapes we could cut out.)
  • HeatnBond Soft Stretch Ultra fusible web adhesive

Decorate the Onesie:

1. Cut out fabric shapes at least 1/4" larger than their finished size. Cut pieces of fusible web the same size.

TIP: It's easiest to start with squares or rectangles, then cut around shapes later.

2. Following manufacturer's instructions, press fusible-web shape onto wrong side of fabric shapes.

 TIP: HeatnBond Soft Stretch uses high heat and no steam to adhere the paper-backed fusible web to the fabric.

3. Cut out shapes the size you want. We cut around the animals, leaving a little color to help them stand out on the white onesie. The paper-backed fusible web helps stabilize the fabric for easier cutting.

4. Peel off the paper backing from the fused fabric shape.

5. Position the shape where you want it on the onesie. Following manufacturer's instructions, fuse the shape in place to complete the onesie.


TIP: HeatnBond Soft Stretch uses high heat and steam to adhere the fused shape to another fabric.

More About HeatnBond Soft Stretch Ultra Fusible Web:

Why We Love It:

  • HeatnBond Soft Stretch Ultra is specifically designed for stretch fabric like flannel and knit (what we used in this project), jersey, denim, and fleece. (See how it works below!)
  • The fusible maintains a strong bond while moving with your fabric for no bulk or stiffness after fusing.
  • It's a permanent adhesive and doesn't require any sewing to keep the fabric shape in place.
  • It's washable. Wash in cold water on the delicate cycle, and tumble dry low.
