I know you are looking for wood plans but I am still a fan of the 55 gal barrels for saddles and blankets. They can be painted so cute(ours had a "neck and legs" of angle iron and a mail box for a head). We had a "pinto" and a "paint" , and an appy(leopard). They had manes and tails too! LOL And then there is all the storage space inside the barrel for brushes, hoof picks etc. Also had shelves in ours(one shelf in each one) and that was cool too. Room for horse treats and if you use the lid they are varmit tight. Have fun.....LQ
