Built some basic barrels and walkways for my son and his D&D group to use in their games. They were fun to make and didn't take very long.
The walkways are made from, tapers, coffee stirrers and bamboo skewers.
The barrels are all made from Das mixed with PVA for some added flexibility and longer working time.
Looking back on these they could have been better, sorry Tom, so I may have to add some more details before he gets them. Always different seeing something you've made blown up on a screen in front of you. Brings out my critical side :-)
