If you’re buying raw veneer this tutorial may be useful:
I had pretty good success with it. Follow the instructions exactly, don’t use steam, clamp the veneer down before applying glue so it won’t curl too severely.
Consider buying a cheap iron for it, there is a nonzero chance you’re going to get glue on it.
Thanks.
Would also add when getting an iron, find one without steam holes–not only cheaper, but will provide even pressure/heat.
I got one like this when I started embossing velvet & leather to avoid puckers due to the holes in sole plate–but also why pay for a feature you’ll never use for the application? (though they are harder to find that those w/ steam option).
What heat setting do you use? I don’t think he mentioned it in the video.
He said the highest setting.
Thanks! I rewound a couple of times and still missed it. The dog and cats were having their morning “romp over the humans in bed” fun, so it wasn’t the best time to try to focus. 
Yeah I used “linen”. Highest setting. I used wood glue but you can apparently do this with standard PVA glue like Elmer’s.
Thanks for sharing!
