Thank you Heather. My mum planted all the trees over twenty years ago, she'd be amazed if she could see it now (hopefully she can!) because it's an actual wood that you can walk through. It has ash, oak, sycamore, hawthorn, hazel, willow, sweet chestnut and beech. Yes I made the oak pens from branch wood. The oak is so hard it doesn't break so easily. I'm glad you got your pen problems sorted out. I think I just won't bother with slimline pens anymore!
