I think the hardest part of making this table was making it square. I think a tutorial video would be very beneficial. Took me a while to make due to life priorities, but it is finally done! Kids have already taken it over! My favorite part is letting them draw on it and make it theirs. Will be fun in the future to look back. We also wrote the date on it. I do think clamping is a must. I didn't do that at first and ended up taking the top apart and redueing it with clamps and glue.
I didn't want cracks that food could get into, and those 2x4's are rounded. So I ran those boards through a table saw to make sure they are flush with the 1x6's.
