DIY baby onesie vest

I recently had oral surgery, so on my down time I've been practicing my sewing. My first project I did was a onesie vest and tie combo for a friends baby. As I've said before--I'm new to sewing so if I can do this, so can you! Although I will tell you, this was my most challenging project to date.
I found the tutorial from this website (Onsie vest tutorial.)

Mine is a little different, I wanted my vest to go all the way to the top of the onesie and I added a tie from ribbon.

I made the inside and outside of my vest from old men's shirts I found at a local Good Will (each $2.99)
The tie I folded into a point at the bottom and ran a stitch, and pinched at the top to create a ''tie" look. I then put a stitch in to hold the tie part and ran a stitch across the top.

As a beginner sewer, I will say that I had the hardest part with all the corners in the vest, if you are a regular sewer than this will be a breeze for you!

Happy sewing!
