StitchWitch – welcome! Once 20 (or any multiple of 10) minis are called, the original poster will close the thread. Vikki dyes the floss after thread is closed. Then she will post a reply here that it has been dyed. You can place your order at that point by going to the Silk Floss section on the main page. If you have called minis in different topics, you should be able to combine them all into one order.
Posting the image of Examplar Sea Foam here (note: Ocean Foam was changed to Sea Foam back then).
