You cannot.
Most people "trap" the farmer by surrounding them with haybales or other items
no.
No you can't. You can only put them side by side.
check out the video on this site they show you how to stack the fences and one shows you how to stack the hay (scroll down to almost the center of the page)http://blog.games.com/tag/farmville/
You cant, not really any ways. Objects or animals cant be stacked or on other objects or animals. it may appear that things are on top of things, but that's when there is a glitch in the game.
Farmville does not allow you to "stack" objects. I presented them with the suggestion as I have an over abundance of hay bales. No answer as yet.
No, you cannot stack fences in FarmVille. What you do is creating the illusion of stacking fences and also hedges.To create this illusion I added two videos that can help you to:How to stack fences, to create buildings or nice landscapesHow to stack hedges to add a 3d look to your farmHow to create the hole illusion in your farm... is amazingHow to stack hay balesSo see the related links in this page and see for yourself how to decorate your farm even better.
You can't. You can place one behind the other so that it looks like you did... But he truth is you can't.
try chucking 80 lb haybales
you jump between them
You get in the middle of them and push them apart.
Its just an illusion, you cant actually stack them. They are just placed at the correct angle to make it look like they are stacked.
