Please help

Hi I'm new to all this so pleas excuse my ignorance

I have enjoyed reading your helpful tips. I have a question, could you tell a complete beginner like me, what size is best to create a work of art in Photoshop that would be a good quality image when it is printed out at the size of 10 x 8 inches.

If you could help me, I’d really appreciate it.

Thanks... David

Doesn't have as much to do with size as it does dpi. When you create a new image in Photoshop - set the size to 8x10 and move the dpi from 72 to at least 150.
