On Saturday, I led the first DIY Flagstone class of the season at the NC Arboretum. Ten people took part in the workshop which started at 9 and lasted until 4. In the morning we looked at several samples in a slideshow and discussed the stones, tools and structural elements of a good drystone patio. Just before lunch, we reviewed the safety concerns we might encounter working together. After lunch we headed outside to the ‘Stone Classroom’, a corner of the Arboretum grounds where they have built a gigantic sandbox for paving projects. After a couple of demos, people worked in teams of two to build their own section of flagstone patio. People had fun and did some great, creative work.
