stenciling question

[shellazure.livejournal.com]

I'm new to the whole stenciling thing but don't worry, this has nothing to do with a "how do i..." question. this is more a prior experience thing.

I'll be spending my summer in Qatar, and my laundry will be done by the marriott hotel there, which cleans absolutely everything on the "hothothot" setting since the water comes out hot anyway and it's cheaper than trying to cool it (it is the desert). So I'm looking for those who have had their self-made stenciled shirts washed on something besides cold and delicate. I can't hand=wash them bc it's a five or so minute walk to the bathroom and the sinks are tiny. Can my stuff survive? I mean sure it's just paint on a cheap hanes boy's undershirt, but I'd like to preserve my efforts if at all possible. I'm just wondering if y'all think they can make it through the summer.
Thanks for any input!
