A palster is an obsolete term for a pilgrim's staff.
well i have recently took some first aid training and what i would do i put a palster over it so it would stop you from picking it and it should heal but if it doesn't ever heal see a doctor . x glad 2 help you
I would say ones that have study thick branches. Some people say maple oak or banyan because they would have lots of support. Be careful, becasue if you choose a fast growing tree, the tree might out grow the house. If your looking for a custom tree house and you live in the UK try this site: http://www.freespiritspheres.com/index.htm I'm not sure where this site is from... but they look really cool. http://www.treehouse-company.com/index.cfm All these come with a big price tag. The first is retro, but quite cosey. The second is custom made to suit your tree. Would you by any chance know of any custom made tree house makers in Austrlaia?
