Many customers have asked for the colors I used in my version of The Drawn Thread's An Open Heart. I used all Au ver a soie Soie 100/3 thread, which is a buttohole twist thread. You can use more than one strand and I did so for all of the whitework border. You do have to lay this thread when using more than a single strand since it is very round and if they wrap over each other you will not be pleased with the look. You'll need 3 spools of the Creme since it gets used for the whitework border and it'll use all of 2 spools and a small amount of the third one. You may need two spools of the #557 as well. I used a single strand for most of my stitches on 34 count but in places I used 2 strands because I liked the more dense look the stitching gave with 2 strands.
