Let’s hit rewind…
In my last post – I talked about this one supply that every watercolorist seems to own – but few actually talk about. If you have already read that post – you know that the supply I’m talking about is a stretching board. If you want to know the reasons why that supply is so crucial – make sure to check out my previous post.

Building your own stretching board…
In today’s post – I’m gonna be simplifying my approach to building a stretching board. So here are the steps to DIYing your own watercolor stretching board.
#1: Go to your local hardware store
- And search the lumber area…
#2: Purchase a sheet of birch wood
- While there, look for sheets of birch wood. This wood is known for being water resistant and thus can take a great deal of water abuse – meaning no pools of water sitting behind your paper while you paint.
#3: Have someone cut it down to size
- Next, have someone cut your wood down to whatever size you desire. I cut mine into 2 square sheets, both 19in x 19in. This way I can stretch my larger watercolor sheets of paper but still easily maneuver the board.
#4: Sand the sides and top to smooth out rough edges
- Then, with a sanding block, smooth out any rough edges to prevent splinters from taking residence in your hands.
#5: Wipe clean with a damp rag
- After sanding, wipe clean any dust or other particles.
#6: Paint the surface with chalk paint for a sleek look
- Lastly, paint the surface of your board with some sort of paint. I use chalk paint since it’s not sticky to the touch and I can buy a whole tub of it to re-touch my wood later on. Basically, we want our board surface as dry as possible – allowing both sides of the paper to dry evenly and thus creating less buckling and warping.

#7: Let dry
- And finally, let the board dry thoroughly (I recommend 24hrs) before using it.
And that’s it – you can use this board over and over again for countless paintings. I’ve even used staples in this board for traditional watercolor stretching, as well as just the basic method of taping watercolor paper down with masking tape, and it’s held up fantastically. So needless to say, this board will last you quite a while – so in my opinion it’s worth every penny.
