My friend Tiffany from MyLitter has been posting awesome DIY tee-shirts, water bottles and more. Her secret is a Silhouette Cameo machine. I am sooo tempted to get this “gift” for myself. So many great projects to do with it. THe one below is on sale for 36% off. This is not a Prime item, so just watch the shipping to see if you can get it by Christmas.
Also remember that Amazon prices change unexpectedly, so check current price before purchasing (it might even be lower!)
