I’m new to this forum- so hello to all.  I’m a professional artist, I create landscape paintings on location.  I dabble in woodwork, but mostly am involved in woodwork where it intersects with creating art.  

I’m gluing pre-primed artist grade linen to plywood- which plywood do you recommend?  

It will be for thin panels, sizes are typically from 8×10 in. to 16×20 inches.  I travel some and carry them in slotted boxes, so panels need to be 1/4″ or thinner.  From what I’ve read, cabinet grade Birch is a good choice. I’ve been using plywood from big hardware stores, or pre-cut panels from craft stores.

Here is my list of priorities for canvas and linen substrates, if this helps your recommendation:

1. Longevity, or archival quality, something that won’t fall apart in many years
   
2. Doesn’t easily warp when glue is applied, or when exposed to moisture, won’t break or fold easily
   
3. Budget friendly.  I aim to make a profit from sale of paintings.
   
4. Lightweight- I sometimes carry several panels at once, hiking to a place to paint
   
5. Compact/Thin- I use panels because I can carry a bunch at once if I travel.
   
6. Environmentally friendly, responsible tree sourcing, etc.

There are of course other substrates like MDF, Gatorboard, Dibond, hardboard, etc. each with pros and cons.  Of these I use hardboard often. 

Thanks for input.
