Thanks! The most challenge part of this build is definitely leveling all three legs, no matter how careful and precise I think I was when cutting the lumbers and constructed them, they still came out a tiny bit off. And the "tiny bit off" became noticeable once assembled with stretchers. Used belt sander to take out some feet heights to level, total of six feet to this bench, that's a lot of contact points to consider.
Thanks! Here are the steps I took: 1. stain them in Dark Walnut stain, then apply 1 or 2 coats of Clear Shellac to prevent bleeding 2. apply crackle medium or white school glue, let dry 3. spray chalk paint on(<-- you really have to use chalk paint, not look like chalk paint, or it will not crackle) 4. use detail sander for some area, and wet towel for wet sanding as well 5. do apply either poly or wax to protect your chalk paint
