To get the wrinkles out of heat transfer vinyl on a freshly washed t-shirt you can use one of the two options below:
Option 1) Turn the t-shirt inside out (the vinyl should be on the inside now) and iron it on a low setting.
Option 2) Toss the t-shirt in the dryer for a few minutes (low or medium heat setting) and then hang it to dry.
Option 3) Use a hairdryer on a low setting to warm up the vinyl. Once it has warmed up, smooth out the wrinkles with your hands. Lay it flat and let it cool off.
Tips to Avoid Wrinkles in Heat Transfer Vinyl
Using an Iron with htv
Apply a good amount of pressure while you iron the heat transfer vinyl to the shirt. The more pressure you apply, the better it will adhere to the shirt in a flat and uniform fashion. Remember to use a hard, flat surface to iron the htv to your shirt.
Iron vs Heat Press
If you can upgrade to a heat press, then do it. You will find that a heat press will allow you to apply the htv to your shirts much easier than using an iron and you’ll get better results. Get a small heat press like the Cricut Easy Press if you are only making t-shirts or invest in a bigger all-in-one heat press machine if you plan on branching out from just doing vinyl on shirts.
A bigger, more versatile machine will allow you to make a variety of crafts like sublimation printing and rhinestone embellishments.
