For those of you deciding to paint windows - you want to use "window markers." We bought out iParty cause they were on sale for 99 cents a piece. Not much in them - I've used maybe 14 already - and mostly squeezing them out and not using the actual marker. How are they as a medium? They look and dry like acrylic (and wash off with soap and water - so they're water based), they can get mushy/messy like oils and they're a pain to layer/blend cause they act like dry erase markers on white board. They will erase when you layer so dabbing is best - that's been the most challenging part of working with this medium.
First Day (Monday):
Second Day (Tuesday): (Ok - I took the reference pic of Paul soldering on the first day)
I go back to finish of Friday. It's been a great experience and hopefully will continue that way! I've been getting many compliments while painting it, too!
