Dear clothesontheline
maybe you should consider doing lumen prints(aka sun prints). All you need is expired paper, a piece of plexi to hold it down, and a few items to lay between the paper and plexi(kids choice). Just expose in the sun for anywhere from a few short minutes to several hours. A gentle wash in water, no chems needed, and let dry to finish. If this sounds more interresting (and much easier), contact me and I will donate a large box of paper to your cause. BTW, you can visit the "lumens" group here to see some fantastic results.
