Temporary T-shirt Printing

when you want to make a statement, but only for a bit

we've all seen those Velcro t-shirts where you can rearrange the letters, but eventually the bits get lost. I'm suggesting iron-on temporary letters (and punctuation of course), that let you make a statement that might be poignant today but tomorrow you'll wish would just wash out when you clean the t-shirt - these do exactly that.

"I haven't slept with David Beckham"
"I went to the t-shirt shop and all I got were these lousy temporary letters"
"Rumsfeld for President !"

       What's the mechanism?
jutta, May 10 2004
  

       thanks [zanzibar] - I reckon you could get letters which biodegrade on contact withe the kind of enzymes in washing powder - you wouldn't want the letters leaking in the rain or discotheque now would you ?

       she's up and left us [z], in mid anno....

       Do non-biological washing powders still contain the enzymes to which you refer [neilp]? If not then I suggest they are not appropriate.   

       You could always bolt an etch-a-sketch to the front!

       "Rum __ for ________lent"?
neilp, May 10 2004
  

       [dob] - nah I think that's what makes them non-bio, but I'm sure there's a way....
neilp, May 10 2004
  

       Biological washing powders contain stuff like proteases don't they? So a protein based paper would be needed which wouldn't be good for ironing!   

       You could make it out of cellulose and have a sachet of cellulase to add to your wash.   

       Nice idea(l) though

       Or, of course, statement T-shirts that change in the wash to say something completely different, as selected parts of the design wash out.

       The threads in the fabric already form a cross point matrix. Could you do it electronically by putting electronic-paper dye on the crosspoints?

       Baked. Only yesterday I was pondering a purchase, for one of my many nieces, of just such an item <see link>. It's not quite as freeform as you want, neilp, but I reckon that it can easily be adapted.

       What? No Velcro skull patches?

       Proposed Mechanism : You'll need a stencil set, a bottle of spray on starch and a spray bottle of weak solution iodine.   

       Starch stencil the slogan   

       Iodine spray over the t-shirt.   

       Your slogan is then revealed in wonderful Prussian blue. Simply wash to remove the slogan or spray a fixer to keep.
