- "Heat N Bond" iron-on adhesive. Get the no-sew kind, so it can adhere to both materials
- Stabilizer (found near the Heat N Bond in notions section), or white scrap fabric
- Cotton fabric for cutting out designs
- Cricut (optional)
- Sewing machine
Step 3: Using a satin stitch, or a tight zig-zag stitch, sew along outside edge of design (or you lucky chicas with sergers, go at it!). Be sure to place something on the inside of the onesie to stabilize the sewing (such as stabilizer, or scrap cotton fabric). Stabilizer can be torn off after sewing, but the cotton fabric is meant to stay as something soft against the baby's skin.
Huge, Monumental, Life-Changing (well it changed mine), Major tip! To reduce your chances of sloppy and loose stitches due to the gunking up of your needle as it goes through the Heat N Bond, place wax paper over the top of the bonded onesie, so it can "lubricate" the needle each time it goes through. :) It can be a bit tricky to see exactly where you're going, but you get used to it (see pic below).
