I went to birdieball last year and ordered a 4x10. It is quality. You can build what best suits your needs.

We couldn't come to an agreement to drill 4.25" holes in the hardwood floors but I do have a felt putting map 10x3 feet with holes at one end with rims. It came with a foam pad to add ridges, but the floor is uneven enough that different angles will behave differently enough. It runs 10-11 and I work on distance control. The primary downside is not being able to putt across a slope - since I generally don't leave approach shots below the hole. That would take more like a 10x10 pad and attached to plywood and be able to raise/lower one side or the other.

Handmade
2*6's and 2*4's
Regulation size cups
turf stimps at 11
its 20' by 15'
Can get like a 22 footer

How did you do that?

Purchased a 3x10' bridieball last year. It has worked great. Does well on hard and you can customize to meet your needs .

You can actually use simulator golf to assist in practice putting. If you an do it in 2D then you can in 3D, plus you'll get to play golf to get swings in. Worked for me.

I use a 10x3 Matt as well, but I want a put out with the put out mat those look like a good practice tool.

Great!! Thank you all for your suggestions, I think I have a good idea of what to do now!

I've just got a basic 10 foot putting mat , does the job

I also purchased a 3' x 10' birdie ball and am very happy with it. As was previously mentioned, you can customize it. Go to their website and check it out.

I got a portable 12ftx1ft puting mat with the hole and I realy like it + my mom doesn't care beacuse it does not damige floors. Hope that helps.

BirdieBall makes great products

BirdieBall for me too. I put two 4 x 18 together in my basement at work and its been great.

I also built my own 8' x 15' indoor putting/chipping green in my basement. I ordered turf from company in Georgia. Very happy with it!

Some nice mats there fellas! Got me thinking about a Birdie Ball design myself.
