Nightfall yarns become available once per month. You can wait for the sale day and choose from the available colors (which includes special shades that are not available for preorder), or you can place a preorder to ensure you don't miss the ones you want. Preorders will open again on May 1st. Want an advance notice of each month's sale dates delivered right to your email? Sign up for the mailing list!
It is pathetic how much I want a skein of this yarn! It's pure lust that's all it is.
