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.
Diy horse jump standards! Very simple to build and use for schooling. 10 ft 4x4 cut in two. Use 2x4's for the base as long as you want them. Paint the way you want and drill holes for jump cups to your desired heights. (I used 5/8ths wooden dowels from wal mart and drilled a 5/8ths hole about 2 in. deep into standard.) Put the dowel in with wood glue and left it sticking out about 4 in. Easy and cost less than $20 to make the set!
