Yes. First, you can go to the craft store and purchase a bag of leather remnants. They had mostly light colored straps as there's no white ink in our sublimation printer; so we save darker pieces like this for other projects -- but not on faux-leather (it will melt). A great alternative would be fabric too if that is what floats your boat - just keep in mind it won't work with plastic either.
I always try to keep a small bin of printed sublimation paper mistakes for such experimentation. So next time you accidentally forget to mirror your image before printing, don't throw it away! The recommended temperature is 340 degrees Fahrenheit (or 175 Celsius), which seemed way too low as most substrates press closer the 400 F or 225 C range--but this may be due in part because I'm using flimsy laser printer paper with an oven setting that's much cooler than what should really work well on these types materials.
I found that the hardest part about fixing my leather jacket was finding a way to take off all of its previous owner's tags and stains. One forum I read suggested spraying down with some expensive polymer before applying your own, but this wasn't necessary for me since most commercial fabrics already have such protection built into them by manufacturers these days! Although I have seen a few YouTube tutorials on this and followed the instructions, it didn't work for me. However, when you try out your Silhouette with non-leather material like wood or muslin cloth to see if they are compatible before cutting into leather!
The next step in making earrings is to punch the holes for your wires through a leather strip. Make sure you use an appropriate size hole puncher so that it can go all of the way up into each shape, and make sure not too close or else they'll be too heavy on one side! Now that you have all of your earrings cut out, it's time to decide on a design. If the holiday is coming up and there are certain colors or patterns in mind for what kind of jewelry we want ourselfs then this could be useful! For Independence day though I just happened upon using patriotic prints which looked amazing against leather - so now every summer dress has an additional layer.
Hopefully you have found the perfect time, temperature and pressure for your leather. The recommended temperature is 340 degrees Fahrenheit with light pressure (12 seconds) to ensure that it has a durable finish on both sides of any material - like metal or paper crafting materials! Take your pre-cut earrings and press away; as tempting as this may sound I only do one at a time because seeing them pressed beforehand makes all the difference in making sure they turn out well later when doing more than one piece together.
One of the best materials for sublimating designs on is heat transfer glitter vinyl. It's easy to work with, and it can be easily cut into shape by your regular vinyl cutter when you're making earrings or other jewelry pieces out of this material! I find that triple- thicknesses make for easier handling while trying not damage any edges during cutting; plus they provide more stability if using an embroidery machine (which also works great).
