i usually use pencils and have only ever had a washing problem once, and it was adress.. i think i probably ironed the pin tucks in process....
but lately i have to admit to using frixion pens. they work so well...but i am seriously uncomfortable with them. i suspect they will turn out to be a bad decision, long term and i certainly don't like the amount of waste i am making by using them. (i feel the same guilty ease about spray basting and might try the elmer's idea next time.)
