For this shirt I used Transfermations for dark colors. I either got it at Michael's, Staples, or Walmat, not 100% positive on which.
Normally when you use HTV and even HTV for light colors, you need to mirror the image before you cut. You do not need to mirror the image with HTV for dark colors. I'd always read your instructions to be sure but I've used several brands and none require this.
First, get your image all ready in Silhouette Studio. Get your cut lines situated- if you layered some elements you may need to highlight them and hit "Cut Edge" or whatever works for you. Do not mirror it! Turn on registration marks and print it. I use "Best" settings for quality. You have to use an Inkjet printer. If you've found a brand that works with a laser printer, please share! I've never seen one.
Once it's printed, stick it on your mat and load it into your Cameo. Have your machine scan the registration marks and get your cut settings ready.
Here's a snap of what settings I use. I set it to "Flocked HTV" and then change the blade to 5. That's why it says Custom Media. ***Note- I get a lot of use out of my blades, but when I switched to a new one, I only had to use HTV Smooth settings, blade on 1! Big difference!****
When I'm done I just lift the parchment paper- unlike the Siser Easyweed carrier sheets, it's not going to be sticky to your shirt or anything- and voila, shirt!
This IS a classic example of me arranging things crooked and/or off center, but on a wiggly 3 year old, it's not very noticeable :) With Siser Easyweed and it's sticky sheets I normally line everything up on the floor and then step back and look at it, and then I can just pick up the shirt and move it to the ironing board, but you can't do that with this stuff- no carrier sheet. My only pet peeve.
You'll also probably notice that the fishing line is missing some pieces- in removing the design from the backing that part was just too thin and I went too fast, but oh well. It is what it is. This is a tiny shirt for a tiny little toddler.
