So - not nearly as classy as some of the examples I looked at, but I'm pretty happy with my new terrariums - all four of 'em! We went for a meal at the Bridgewater Inn and wandered around the creek at the back to find, not only a wealth* of moss, but also someone's deserted bonfire!! So we filled our zip-lock bags then poked the fire for a bit before heading home to get all creative!
I also removed the super-daggy curtains in the new sewing room and replaced them with something a bit craftier... call it a work in progress!
* I'm not entirely certain that a 'wealth' of moss is the proper collective noun... Any other suggestions?
