We dyed playsilks a few weeks ago at my parents'. I've been wanting to do this since I saw them here (and then more here). My mom ordered the silks (some 30", some 12") and then I purchased the million packages of Kool-Aid. This was a fun activity and the directions at each of these sites are easy to follow. Now we have a dozen silks for tent-making, dress-up, hairstyling, peek-a-boo, etc., etc. Lots of fun!
The top picture is of our newly dyed silks hanging to dry. The second picture is of the dried silks, sporting a more tie-dyed look since we didn't individually wash the scarves (oops).
Advice: Don't try to dye a dozen silks in one sitting. At least not with small children. It just takes too long. I think 6 would be a lot more doable.
Also, sink or machine wash each scarf individually after dying if you want to avoid the bleeding.
