It might seem silly, but I think I can write a book for a hundred and one uses for 'sticky tack' or 'blue tack'! I wanted to add more colors to my field kit but there are no more places, so I made some! Where the brush should go, I put three little blobs of sticky tack and smooshed them down. I then put just a bit of wet paint into the divided areas and let it dry. Then the little removable water pan (I mean LITTLE!) I've been using for black paint, so I added a little wall to that and added Naples yellow, I thought it would be good for grasses, people etc. I will let you know if it works, the stuff is amazing, really!
This is a page from a little sketchbook where I tested the colors out. I was comparing reds as you can see, which ones were similar so I didn't have to order new paints. (it's not cheap you know!) The colors at the bottom are tube colors I put into a plastic travel palette, (see it at the bottom of the photo of my 'mess') they're like a repeat of the colors in my large studio palette. I want to see if they'll stay put or will they flake off all over the place? The drawing of the beetle I did from a field guide. I always try to grab something to draw when I know I'll be sitting, wasting time in a waiting room. I have a vinyl 'bible' cover that I picked up at Barnes and Noble that fits a 6"x8" sketchbook and across from it a field guide or other book. I'll post pictures of that sometime, it makes a great little travel kit when outfitted with my 'travel art supplies'.
