Hey Jean. What if we try soaking some of those type things in a thinner wash of the concrete after soaking the shoes and other objects in water for a day and draining overnight? With a few more thin layers painted on in the next day or two, we might achieve something like that German man or woman who did those cool ghost clothes..................Hmmmmmmmmmmm.
We would want to drill the drain holes in the bottom first I think.....
