I used string gel along the bottom. Sorta gives it a vegetative look, don't you think? It makes me think of frog eggs. Frogs lay these long, stringy things.
This is what it looked like with the under painting finished. I like the look this rusty, burnt orange paint gives the finished piece. Kinda earthy. I have Liquitex string gel. If you haven't tried it yet, have patience. I used a straw first time and actually sucked the stuff up into the straw, thinking it would drizzle out more evenly. No, don't do it.
It just sat there - in the straw. Just use a stick or tooth pick. Have a wet brush handy to clean off the blobs, if you don't like them. Otherwise just dip the stick and drizzle anywhere you want texture or make a pattern. Like a plaid or flowers. Have fun.
