KnitPicks Dancing is discontinued, any variegated/multi-color sock yarn will do fine as the Main Color. I used 1 skein (253 yds) and 10-15% of the 2nd skein, approx. 300-360 yds.(depending on gauge; personal knitting style, i.e. tight or loose knitter, etc).
KnitPicks Essential Petunia (Contrast Color 1) is also discontinued, sock yarn of choice will, of course be perfect! I used approx 1/2 - 2/3 of the 231 yd./50 gram skein of yarn. Lastly, for Contrast Color 2 I used leftover Opal sock yarn, approx. 70-100 yds.

Perfect pattern for leftover sock yarn!
I found that weaving in the ends of the yarn as I knit was very helpful. I certainly was glad they were all woven in as I made the final toe decrease!

My designs are also available on individual blog posts (as seen below) where you can increase the size of the photos which may be useful in st. pattern definition or a very good look at the design. Or you may find pattern steps detailed; techniques explained; additional pattern notes and/or tips, etc., depending upon the pattern.
