Which is the best ground?

[Tito Champena]

Dear Mike,

I always apply a couple of additional coats of acrylic gesso to my canvas; anyway I'll do the same with the boards. I was debating whether to buy wood or man-made materials. I will try the latter first because they guarantee better rigidity since I'm planning to paint in a technique similar to yours. I will also get the one with linen to prevent problems with adhesion, if there are any.

I will be painting my young granddaughter and I want to make sure she will enjoy the painting by her late grandfather when she becomes an old lady.
