I made the sign almost a month ago I think, so it should have had time to cure I reckon. I'm now wondering if the problem could have been when I washed it after the first two coats I used a 2 in 1 washing capsule so it would have had fabric softener in it. Anyone think that could affect it? If so, anything I do to it now won't work because I've just used the same capsules to wash the whole quilt...Eep! Maybe I need to invest in some washing powder without softener already added?
