This is the sturdiest chair ever! When my daughter was throwing out her wicker chairs that were falling apart I grabbed one for this project. The chair was covered with rat wire and chicken wire. Then I got morter mix and trowled it on, doing a section at a time. Some things to know about concrete are that the less water you use to make it, the stronger it is at the end, and that the slower it dries, the more strength it has at the end. When the sections were drying, I kept them moist to slow the drying. The rounded glass pieces were pressed into the concrete when it was wet. Below is a picture from the start of the project. Now I'm just waiting for someone who wants to come over and 'set' for a while!
