DIY fillers made from pallets. So simple to make your show jumps more exciting. Cut pallet in half, level any odd bits offs. Drill 2 extra pieces of timber to the back just to look nicer and be sturdier. Add feet on each end for stability. Paint with an undercoat then top coat. Could add branches/sticks in the middle to create a brush too.
Mounting Block - good photos with instructions. She made hers for about $20. Might have to try to do this.
Easy Glide Jump - The Easy Glide is great for using as a Jump or for Cavaletti work. It can be rotated on the ground, giving many different height options including 8", 15", 19", 22" and 30".
