I have a collection obsession with Washi Tape. I define it as an obsession because I collect it more than I use it. Washi tape, also known as rice paper tape, is a thin masking tape of sorts with a re-positionable adhesive that comes in a multitude of colors, patterns and designs.
Also in my collection are other similar decorative paper tapes, tissue tapes, one or two cloth tapes and other similar non-Washi tapes in various widths. Very recently Michaels has been stocking dozens of similar craft tapes in their Recollections line. For true Washi tape, I’ve found that the biggest selection is online. There are sellers on Ebay and Etsy that ship from the US and China, so if buying from the latter, you’ll have to be a little more patient for your shipment for the best price. I received a nice fat parcel yesterday that puffed up my selection of tapes considerably, making my first Washi tape storage solution a bit obsolete, sans the perforation blade.
I have this funky flea market wire Tintex dye box display that I’ve used in the past in my little studio to hold jars of bits and bobbles. 
Paired up with a stack of wooden berry baskets that I picked up at an antique store it had even greater potential as a tape organizer.
Now with my Washi tape organized by color in each basket, the wire display is even more spectacular!
What to make with all this Washi tape? Start with Washi Tape Flowers. Or, in lieu of crafting with manufactured Washi tape, you could always make your own paper tape from wrapping paper!
