Well, coming from a place that has long winters I have my little setup in the garage so I can get some practice in during those long 7 months or so. I first tried to use a blanket but soon found them tearing up and falling down, making it hard to focus on my practice. I then bought a $ 30 net that was fairly good for a few months - until I made a hole using my driver. I finally went out and bought a strong net for about $ 150 (2 years now) which I found great. The net is great and the money well spend! I think this site does a decent job (
http://golfnets.org
) and Amazon has some great filters to find cheap well reviewed nets aswell.
If you have figured out a good way to make the cheap blanked method work please share :D but if you are going to practice allot I guess buying quality will only help you improve.
