I hope this is where I put this, but I was wondering if anyone could explain how to wrap polo wraps on all four legs? I have a basic idea, but I don't want to screw my horses and pony up if I wrap something wrong. Thanks.

I'm happy to give you the procedure,but HIGHLY recomend that someone knowledgeable be there to observe or inspect. For as you already know you can do damage if done incorrectly.
Starting @ 1/2" from the top of the knee or hock,on the inside groove of the leg.
Wrap from the front to the back and inside to outside.
Wrap down the leg,keeping each wrap horizontal and parallel to the previous one and overlapping by about 1/2 the width of the bandage.
When wrapping pull backward against the shin,not forward against the tendon,and keep tension even.
At the fetlock joint,drop half the width of the bandage down underneath the joint,bringing it up in front to form an upside V.
It should not be loose, but must not be so tight to restrict movement of the fetlock joint.
Wrap back up the leg, in the same way as going down.
Always finish on the outside of the cannon bone, if its not, re-wrap

Ltc4h said it good. The only thing I would add is that if you are using quilts under the polos make sure that you leave some quilt sticking out at the top and the bottom. This will allow you to wrap fairly snuggly without doing any damage to the leg. If you are doing standing wraps they should be changed and re-wrapped every 24 hours. As far as which direction to go. That is up to you some people say clockwise other counter clockwise. I have been around numerous vets over the years and trainers and it is probably a 50/50 split on which direction they go. The big thing like Ltc4h said is that you put your tension on the front and lay it across the back of the leg. If you can't find some one to help you (trainer, etc.), You can call your vet and have them help you the next time they are out or if they have a clinic normally one of the technicians would be happy to show you.
