Welcome to the forum Kirsty.
You've made a good start by joining here, there a lot of topics which will help and if you have a problem we are more than happy to help you.
The rubber on stilts are great on the hard stuff but not so good on grass. Most poeple cover the hoof with either a tire ( off-road ) but some use Jasons " Hoofies "
Learning on your own is hard if you can find a local group join them, we enjoy meeting new people and you'll pick a lot up from watching others.
There's not many near you but it's like a snow ball once they see you more will follow, you'll not be a Tigger for too long.
