Learn all you need to know about laying a patio from the foundation up in this hands-on, two session workshop with Jim Baker of Native Landscaping.  The workshops will take place at Tower Hill Botanic Garden in Boylston on Wednesday, October 27 from 6 – 9, and Saturday, October 30, from 10 – 2.  You may register ($54 for THBG members, $60 for non-members) at www.towerhillbg.org.  Getting your plans approved by the Back Bay Architectural Commission, however, is not part of the curriculum.
