Let's face it. Everyone who has tried markers has an opinion on how they work, experts and novices alike. My thought is to question the use of the quilt. Is this an heirloom gift that will probably never be washed? Or is it a baby/lap quilt that could be washed under fairly harsh conditions every week? Test the marker you want to use on scrap fabric, then decide. So many of these products have been very recently developed, so don't have the advantage of long term evaluation. If I were making an heirloom quilt, I'd be inclined to stick with something that might be a little more difficult in the short term but will hold up better long term. Something that will be used and washed regularly may wash out any residual chemical before it can do any long term damage. All that being said, you have to do what you are comfortable with.
