The quilt is fantastic. You did a beautiful job. I am so sorry that you have had the problem with the blue marker. I use the Frixion pen and don't have any problem with ironing it and it still comes out after washing. Not that it helps you with this one. I hope you are able to get it out. I was wondering what motif you used for the corner feather? Is there a pattern for it? I could probably free-hand, but would prefer a pattern. It is for my father-in-laws quilt for Christmas.
