Looks good, thanks for sharing. LMK if you want the file for my own t-shirt T ruler.
If you’re making a lot of copies of the same kind of shirt, I found this method to be super helpful. It can take a little while to make the cardboard template just right, but once you have it, it makes placing the design much much faster.
I never shared pics of newer versions…
The transfer goes under the ruler, with the top of the art matching the cutouts in the cardboard. I put a tiny bit of repositionable adhesive under the ruler to barely hold the transfer in place. Not too much… you don’t want residue on top of the transfer. But you should be pressing with a Teflon sheet so nothing gets on your platen anyway.
The ruler is sized so that when the top touches the bottom center of the neckline, the design has the right vertical placement. I use the ruler marks to get it centered side to side relative to the sleeve seams. (Or, like the templates in the thread above, I might use a weird shape to help center things.) Then, I hold the transfer down with one hand and peel the ruler up and off. Then it’s ready to press.
What your template looks like will depend on your design and the garment, but this should give you something to think about.
