Put stepping stones in your garden, and make sure you land on them when you go over the chicken wire. CW is 4 ft, but 1ft should be underground, so 3ft to hurdle. If you are short, put a stepping stone on the outside also. Avoid wearing flowing skirts or anything that might get tangled in the CW.

Leave one end of the fence not attached to anything. Buy some j hooks at the hardware store. Attach them to you last upright and just pull the CW over the j hook to attach and anchor in place. When you want to get in. Pull the CW off the j hook. Easy and simple.

That is if your too short to step over. Or you could trim the CW down to say 2 feet on one spot for an entrance/exit.
