If you work with heat transfer vinyl or sublimation, this alignment ruler set will save you so much time and frustration! The 9-piece kit includes 8 different sized rulers for adult, youth, toddler, and infant shirts, plus a measuring tape. Made from flexible PVC with clear printed scales, these guides help you center designs perfectly every time. Just line up the ruler with the shirt collar, position your design, and you're ready to press - no more crooked placements! The different sizes ensure you have the right guide for any project, from baby onesies to adult tees. They're reusable, easy to clean, and much more accurate than eyeballing it. Perfect for Cricut users, small business owners, or anyone who does custom shirts regularly. Just remember to remove the ruler before pressing - melting plastic is no fun! This is one of those simple tools that makes a huge difference in your finished product quality. Your shirts will look professional every time, and you'll wonder how you ever managed without these guides!
