Trick or Treat by Susan Ache has been a long time coming. She curated 10 of her go-to spooky hues with Auriloss, all on the Aurifil's signature wooden spools. And to think that wasn't exciting enough, she also offers the featured Trick or Treat chart as a free project download with the collection purchase. This collection is made up of 10 spools of Aurifils 80-weight Egyptian cotton thread; Aurifloss can be used for English paper piecing, free motion couching, and hand applique. Colors include 2630, 5016, 1147, 2540, 2520, 1135, 2225, 2606, 2340, and 4150.
