I used the small soaker hose; formed a curve, placed the ends down in the bowl I was using, and did my best to surround it with the hypertufa mix. Actually, if this is understandable via typewritten message, I cut the ends of the soaker hose that went down into the bowl in half. so only a half portion of the hose is cemented in the mix (otherwise, it tended to want to come through the mix toward the center of the form). But even when I took the piece out of the form (the bowls of different shapes), I would have some open space with soaker hose exposed. I had to second coat it with thinner mix with no vermiculite or perlite in the mix, and had I had sand, I would have used that for second coating. To cover the soaker hose, I cut strips of cloth, coated them with mix, and wrapped them around the handle after the hyper-tufa mix was firmly set. I'm still in that process on a few of the second painting coat of the handle. Those are shallow bowls, suitable mostly only for succulents. I've got a couple larger baskets in the works, using the same method, but deep containers in hopes of potting a larger plant needing more root space, and more for use indoors, where the current photo ones were designed to stay outdoors.
For those wanting to make a miniature garden, here's an idea you can make yourself. Buttons were used for the table and chairs, with thick craft copper wire. An umbrella could also be made. [I know this is not exactly cloth and cement, but these could be used *in* your cloth-cement pieces.
