OK - a mister is a spray bottle that emits a fine, almost fog-like spray of water as opposed to a coarse stream. They are used for plants (like orchids) that need high humidity. Can buy them in art supply stores, but will be cheaper in a garden center or WalMart. May even find them at dollar stores. You can also lightly spray the surface of your painting to keep it from drying too quickly as you work. For a limp canvas, you want the rear to be damp, but not to the point where the water is running off the surface. You can do it before you paint or after the fact as needed.
My sister-in-law lives in the "Valley" and does water soluble oils. She gets most of her supplies from an outfit in ON rather than pay the inflated Michael's prices. Will see if I can get the addy and pass it along.
Hi Catherine! I like your "Birches" painting. From the photo, it appears to be done on a stretched canvas (there is a vertical line on the left side in the photo). The line that shows up like this is due to the canvas being a little "limp" and not completely taut. There is an easy fix for this. Simply use a mister and dampen the entire rear surface of the canvas with water. As the canvas dries out, the fibers will shrink and regain the needed tension.
Welcome, Catherine! Nice photo of Peggy's Cove too!
I grew up in Dartmouth, and have a lot of relatives along the South Shore. Went from there to Sarnia ON and currently in central NY State. I started with oils in high school and flipped to acrylics shortly after they became available because I liked doing knife painting. Oils just took an eternity to dry, and often cracked in the process.
Getting back in to painting now that retirement is a reality; things have changed a lot in the interim. Karen's site has a lot of nice folks on board, and we do learn a lot from each other. Don't be bashful about asking questions; makes us all think about our own practices. There are some free "tutorials" that Karen has done up, and they can be a big help when starting out (or re-starting).
