I did this tutorial on Instagram (mainly because I left my camera at my mums house) but you can also now find it on our Facebook page here: https://www.facebook.com/pg/chestnutridgemodels/photos/?tab=album&album_id=10154236520616482
It will show you how to simply adapt the Breyer Cross Country Jump (which you can find for sale here: http://www.chestnutridge.co.uk/cross-country-jump-34755-p.asp ) to make it performance ready.
Basically just lollipop sticks and card! It's a really lovely jump. Think I'm going to have to invest in a decent tack set and rider for 2017 now!
