Canson Mi-Teintes has always been a staple in my drawing classes back in college up until now in my various projects. The sad thing about it is, college is many, many eclipses ago and I still don't know how to pronounce it correctly. I googled it this afternoon and found a forum discussing this.
And the poster, Kate Mc, said that it's pronounced as:Me Taunt, with a tiny 'uh' after the final t. Sandge, you need the final "t" sound because of the "-es" on the end. In French, Mi-teintes means
"half tints or half shades".
Ok, I'll use that until someone else says otherwise. :)
