I also own the same baby boy motif, that Michelle is working with, so I will use it for this tutorial.
What Michelle wants to do seems like it should work by just duplicating the design and pulling the corner so it's larger, but the design doesn't adjust proportionally as you can see in the image below.
The onesie came out so cute and would make a perfect gift tag or even a 'clothesline' garland for a baby shower if you strung a bunch of them together.
Thanks for coming to class today at Silhouette School. If you like what you see, I'd love for you to pin it!
