This endeavor turned out to be more tricky than I expected. I tried every manner of transfer for the designs but none were completely satisfactory. And the smaller the design, the harder it became to get a clear image on the t-shirt fabric. I finally got an acceptable design to follow by using a Clover transfer pen. I also tried using some Super Solvy fabric stabilizer on the back of the onesie, but I became frustrated with it and abandoned its use after completing the first design.
My other challenge with these tiny designs was the stitching itself. I generally use a basic outline stitch, but on these designs it was much trickier than I expected. I ended up with a mixture of outline and running stitches, but I still wasn't completely satisfied. I did, however, finish all three and popped them into the mail yesterday. Whew!
Now, back to knitting!
