I got sick of other brands out there that have their own die-cutting machines going the "cheap" route with their vinyl and cutting corners so I started my own line of HIGH QUALITY adhesive vinyl that is MADE IN the USA! Angel Craft VINYL is made to last with premium quality and a strong 3 mil thickness. It is best used for INDOOR applications, but can also be used OUTDOOR depending on weather conditions. Once you order and it arrives to your home just remove the plastic wrapping and attach it to a roll feeder or use in Provo Craft CRICUT machine or the Silhouette CAMEO / PORTRAIT die cutter or any other printer that you desire. After you have cut your designs you then can use the Angel craft Transfer Paper (sold separately) to easily align your design on the wall or other smooth surfaces. WHY 6.4cm CORE. Vinyl has memory, which means it will roll back up to its original position. However, with a larger & thick core it is less likely to roll back up as tightly compared to smaller cores. This IMPROVES "stability" and "cutting" on different roll feeders and vinyl cutting machines!!! Great for Home Decor, Weddings, Scrapbooking, Stencilling, Papercrafting, Signs, Windows, Glasses, Tiles, and so much more! Go Ahead and add it to your cart and try it out for yourself. You will NOT be disappointed!
