Join Lulu Ferris to watch the complete class and sew along at your own pace.
What you’ll make
The Leo is a baby romper with shoulder straps, snap closures, fitted leg bands, and an optional kangaroo pocket across the front.
The pattern covers preemie through 24/36 months. Its simple shape makes a lightweight one-piece outfit, especially when sewn in a comfortable knit.
Explore another one-piece style with the Teddy baby romper.
Pair the Ellis shorts with the sleeveless T-shirt.
Another option is the loose-fit T-shirt with back snaps.
What you’ll learn in this class
- Sew and turn narrow shoulder straps.
- Attach the facings while securing the straps.
- Prepare and topstitch the optional kangaroo pocket.
- Join the side and crotch seams while anchoring the facings.
- Stretch and attach smaller knit bands to the leg openings.
- Install snaps and reinforce fine fabric when needed.
Fabric and supplies
A knit is the quickest option. Use a ballpoint or Stretch needle and finish seams with an overlock, an elastic stitch, or the demonstrated straight-stitch and zigzag method.
Woven fabric can also work, but the leg finish must be adapted. The class explains using a band sized to the leg opening with elastic instead of relying on knit recovery.
Make it your own
Leave off the kangaroo pocket or replace it with a small side pocket. Contrast topstitching or a decorative stitch can highlight the pocket edge.
Use snaps at the straps, or substitute buttonholes and buttons. For a very fine knit, add a small fabric reinforcement behind each snap to reduce strain.
Sizing
The included pattern ranges from preemie through 24/36 months.
The class covers the straps, facings, optional pocket, leg bands, and closures, including the adjustments needed when substituting woven fabric.
