Okay, if you're into t-shirt crafting, this CCINEE alignment ruler set is a total game-changer! Whether you're a pro or just starting out, these rulers make centering designs so much easier. You get 4 different sizes in one set - perfect for adult, youth, toddler, and infant shirts. No more eyeballing and ending up with crooked designs! They're made from sturdy PVC that's flexible but durable enough for multiple uses. The clear printing makes them easy to read and line up perfectly. Just align the ruler to the collar, center your design, and you're ready to press. Works great for sublimation, heat transfer vinyl, screen printing, and all kinds of craft projects. Seriously cuts down on wasted transfers and messed-up shirts. Remember to remove the ruler before actually pressing though! So much better than trying to measure and mark each shirt individually. Your designs will look professional every time without the headache of guesswork.
