Sleeveless Onsie from Adult T-Shirt


I found this cute idea for a shortall on Pinterest. It’s by Heather of Feather’s Flights and she made a great tutorial and pattern. Check her’s out here. I had some ideas of how I wanted to change it, so here’s what I did.

I didn’t use her pattern, although I’m sure it would be easier (I haven’t had ink in my printer for quite awhile now, it would have been easier but at least it makes me think creatively!). I used one the baby already had and traced it onto tissue paper. I made sure to add quite a bit of space on each side, because I wanted him to have room to grow and for my seam allowance. I also was planning on making a tank top, so there was extra space on the sides of the neck.

The onsie I was copying didn’t have the extra piece that Heather had on hers, it was just the front and the back pieces, the same shape. After cutting out the pattern I pinned it to the front of the t-shirt and cut it out of the shirt.

Next I cut the neckline and just cut a little bit off of each side and then pin it back together and sew it.

The sides also need to be sewn, put the two pieces with outsides facing in together, then pin and sew the sides, starting under the arm hole.

The next thing is to hem the legs and arm holes. I did just a single fold under and stitched it.

Next it is time to figure out the snaps. I used snap tape and sewed it on by first pinning one side to the bottom, but with both outsides facing in. I stitched one side and then turned it over so insides were both inside and stitched it closed. For the bottom snaps I pinned them outsides facing in and just stitched it once. Now when they snap the tape isn’t very visible.
