I signed up for Marla Baggetta‘s class “Adventures in Acrylics“. The first demo she provides is treating acrylics rather like watercolors, and building up glazes of a single pear, and a group of 3 pears. So, before I watched her video demo, I did my own interpretation.
I have two pear paintings which I did side by side: one is on gessoboard (which I mostly haven’t used so far) and one is an 8×8 “super saver” cotton canvas from Dick Blick. I find the paint slips and slides more on the gessoboard; something I find irritating in my beginner-ness.
That said, on the whole, I prefer the pear I did on the gessoboard; it’s a more accurate shape. (I actually sketched the pear with an HB pencil in that version. In the other, I just painted the shape with a bit of yellow ochre paint.)
Otherwise, I did the same process and used the same colors on both substrates, finishing off with a satin gloss.
