How to Cut and Apply Heat Transfer Vinyl

Design

Create your design in your studio software.

Once it is completed, you want to select your image and flip it horizontally.

You can print multiple designs at once, it's easier to weed if you draw a cut line between the images.

When you go to print (on a Silhouette) it worked well for me to:
Choose Heat Transfer Material-Smooth
Print with the blade at a 3 (I like it to be this high and I find it doesn't cut too deep),
Speed 10
Thickness 6

I haven't done glitter but online I saw that you want to choose:
Choose Heat Transfer Material-Smooth
Print with the blade at a 3-4,
Speed 5
Thickness 33

Place you vinyl down with the plastic side on the sticky part of your cutting mat, vinyl side up.

Cut.

Weed.

Iron:

Make sure there is no water in your iron to create steam. Heat your iron to 300-325 degrees, partway between the cotton and wool setting.

Lay a protector down on your surface. I used a large square trivet with a towel on top. place your fabric on top. If it's a humid day, you are going to want to iron any extra out of your material first.

Lay your vinyl face down on your fabric, using a measuring tape and or folding the fabric in the middle help with even placement.

Place your heat press transfer sheet (Teflon sheet or thin towel) over the top of the vinyl place on fabric.

Hold your iron down, pressing hard into the fabric on each section for 15-20 seconds. If you hear a crinkling of the plastic the vinyl is attach to, you know you are pressing for too long. You want to be able to pull up the plastic, without pulling the vinyl up. The vinyl should be adhering into the fibers of the fabric, which can be difficult to tell.

Care of heat transfer vinyl fabrics:

Don't wash within 24 hours
Wash cold inside out
Hang dry or tumble dry-low
A lot of sites say do not use fabric softeners as well
Do not iron or dry clean
