I bought a pattern called Aunt Bea's Parlor which is a hand embroidered quilt that I saw here on the QB and fell in love with. The pattern was $15, which is steep to me. Then when I opened it up, you are supposed to trace it with a macron pen onto your fabric. What's up? I googled macron pens and they say they are permanent ink. The pattern says use black. I don't mean to be disrespectful, but will this really work??!! Will my thread cover all black marks? I am an excellent embroiderer but this makes me a bit nervous. I don't want ANY black showing and would actually prefer that all of the ink washed out. Any other ideas? I wanted to take a few blocks with me on vacation next week- so am hoping for an answer soon from someone who knows. Thanks!
