Sorry - my referencing the word 'tiles' is not referring to ceramic or porcelain tiles. It is simply what Shelli & the host of Scrapbooking called these wonderful little embellishments.
Here's the technique on DIY that Shelli demo'd:
1. Stamp letter or image on regular cardstock. It looked like they used marvelous magenta on us white.
2. Using wire (looked like she used the 22 gauge silver from wire works), wrap around anything cylindrical. Shelli demo'd how to do this with the cap from the stampin' mist spray bottle. The ends of the wire do not have to be connected, just touching.
(She also had a sample using the flower from All the Best and maybe used the refill bottle from Stampin Mist for a guide - it was a big 'tile').
3. You can wrap the wire around the cylinder repeatedly to make a number of circles. To make the circles, simply cut the spiral apart. Think jumprings. Just snip up the spiral to separate into individual rings.
4. On a flat surface, lay one wire circle on the cs around the stamped image.
5. Apply crystal effects inside the wire circle, being rather generous with the medium. The ce will build up and stay within the wire border magically!
6. Allow to dry approx. 30 minutes to an hour. I have had these things take hours to dry, depending on the thickness & I would wager humidity and temperature are also varying factors.
7. Cut out along the outside of the wire and BAM you have an accent. Affix with mono adhesive or a pop dot.
There are a few samples in the gallery using these nifty things. Here is one by Kim Wilson:
