so i decided to contribute with a hole also, but this one is not from play but FOR play! and it's not going to be just for marbles!
i used a forstner drill bit so i could cover it up with a faux wood knot
...St just loves to just drop the marbles into the hole
(we put a bowl underneath the hole to catch the marbles)
p.s. i plan on making some interchangable wood knots
for other activities...and maybe some more holes ;)
