Materials:
- Cricut machine
- Silkscreen mesh (Amazon)
- Heat Transfer Vinyl
- Underglaze
- Silkscreen medium
Step 1: Select a design from my website. I’ve created them to be cricut friendly. You will find them under “Artistic Resources”
Step 2: Cut your design out with the cricut onto HTV (Heat Transfer Vinyl) and weed away the areas that you want the underglaze to pass.
(these are the images taken from my website. I cut them on the cricut and weeded the area I wanted the underglaze to pass through)
Step 3: Use an iron to press the HTV onto the silkscreen. Check the temp and time for the HTV, each brand is different. I prefer to use the cricut iron because it doesn’t have holes in the bottom and makes the process a lot smoother. I also use a towel under the silkscreen and parchment paper between the iron and design. If you are not familiar with HTV it will probably have a protective layer that you will have to remove after you’ve ironed it to the silkscreen. 
This is the silkscreen mesh. It needs to be ironed to make a good silkscreen. The photo below is after I have ironed it.
Place a towel on the floor, then your silkscreen mesh, then your HTV.

Step 4: Once your finished the silkscreen is ready to use! You can use it to transfer a design directly to clay or you can create underglaze transfers. It can take a bit of practice at first to get a nice transfer. Initially it would be helpful to use silkscreen medium (by Mayco) to thicken your underglaze. After many years of practice I just let my underglaze dry to the thickness of peanut butter and it works great without any silkscreen medium. 
This is the design I will use. I have cut out all the silkscreens so they are separate and easier to use. 
This is the consistency of the underglaze I use for transfers. This was done by letting it dry out, but Mayco silkscreen medium is an easier alternative.
Hold the silkscreen in place with one hand.
Apply the underglaze with your finger.
Once you apply a little, it will help the silkscreen stick to the clay so it doesn’t move around and ruin the transfer.

I’m putting a black transfer in black underglaze because I want to carve around the design.
Step 5: If you are just starting out with this technique it is best to practice on bisque, the transfer is easier and you can wash it off if it doesn’t work correctly. If you are using it for sgraffito you will have to do the transfer on leatherhard clay.
I outline the transfer
and carve away the areas I want white.
Step 6: You can now use your silkscreens for
- underglaze transfers
- sgraffito
- Outlines for underglaze painting
- relief carving
- an outline for Slip trailing
- glazing
- Merch for your store (T-shirts etc.)
With these easy steps, you can create your own custom silkscreen designs using your Cricut machine. Experiment and practice! Happy printing!
