Rainbow Fabric...Tape...Stuff
What is it? It's called Ticker Tape™, and it's a velvety nylon fabric, slightly stretchy and yarn-like, but flat, like tape. And light enough to be crocheted, we think. Cold-water washable. And it's from Italy, so it's really pretty. Whatever it is, it's by Moda-Dea™ and mighty craft-friendly. Approx 1/4" wide, you'll get (67) yards of it that segue through a series of hues. The Tropical Tape runs through leaf-green/yellow-gold/red-orange/orchid. The Festival Tape morphs through purple/red/turquoise. The Charade Tape blends red/green/orange/blue/purple.
