Tried going for a stippled effect with the thread- it took forever! I used stick-solvy on this and now the fabric looks a bit discolored - I’m not sure if that is the reason or if it is just from shoving it in my bag etc while I was working on it, but does anyone have any good cleaning tips? Just handwashing the whole thing or using like a stain stick? I’m a bit afraid i will ruin it after spending so much time on it. TIA
