I've used the colors as well and they work great! I love the fact that we have a lot of different colors to choose from and the price is right--I don't feel like we are "gouged"as quilters! Probably the whole set of markers costs what a specialty quilting pen costs.
I haven't come across the problem of ironing over the markers, though. I usually use them at the end of the piecing process for the quilting part...once the ironing is done. Then, I wash. Not a problem yet, for which I am thankful!
And oh, I just used pink a few days ago...no problems at all with it washing out. I use soap, and I don't iron over the color usually.
