Very, very helpful. I'm doing a portrait for the first time in years and it's of a retired principal of my school that will hang in the library next to 3 others painted by my predecessor and Art teacher. No pressure!
It does certainly take time and effort :) Here is a video tutorial where I show and explain the drawing process: nicolesleethatelier.com/register/preparing-a-drawing-for-canvas-transfer/ and here is how I transferred the drawing: nicolesleethatelier.com/register/ftgu1/
You mentioned that problems occur with the wrong ratio of paint and mineral spirits. How do you know the right ratio? I tried this... After it dried, the paint just rubbed off! I removed all I could get off so I could try again. I don't know for sure what I did wrong.
That has happened to me too, it means there is too much solvent. There should be more than 50% paint, and as little solvent as possible. I like to add a little bit of Gamblin Galkyd to the underpainting mixture, to ensure adhesion to the canvas. These are very rough estimates, but I would guess my underpainting mixture is about 65% paint, 10% galkyd, and 25% solvent (just a rough ballpark figure).

i prefer the underpainitng, without further passes. The paint is liscious and your technique leads to a beautiful, expressive painting.

Thank you so much! Most seasoned painters just "feel" when it is right, but beginners can't do that.
