Baby craft question

[bluehwys.livejournal.com]

I was wondering if anyone could tell me if iron-on letters and such are baby safe. I have a friend who's pregnant and I wanted to decorate some onesies for her, but I'm not talented enough to stencil or silkscreen. I looked at the packages at Joann's, but saw nothing about non-toxic or anything. Also, if I go with the iron-ons, can they be washed on delicate instead of hand wash like the packages say?
