For large quilts it takes more room than a long arm. Think about it, you are guiding the quilt from one end to the other thru your sewing machine. You need a large table and you have to have pvc pipes to roll on the table to keep the frame on. You cannot hold the thing up without the pvc pipes to roll on. My pvc kept falling off the table as they dont roll straight.
It is fine for small quilts but so is your sewing machine. Free motion for small quilts works fine on your regular sewing table.

I'm interested to read these comments as I've watched the video online and they make it look easy but I've been skeptical. I don't think it looks like it's worth the money.

snow, do you still have the quilting frame ?

I am so excited Snow thanks so much for sending me the frame. Can't wait to get busy quilting a top. I'm trying to leave you feedback BUT can't figure out how. I went to your profile that feedback score but can't see where it says leave feedback. its driving me nuts

DO YOU STILL HAVE JF Multi-frame system?

I did want one now I don't know what to do. Some DO AND SOME DON'T??????

I think you may be right. I had a lot of customers who were dissatisfied with the Flynn system....I don't have personal experience with it, though.

If you look at the thread about things that you bought and regretted there are a bunch of comments about it.

I had one...used it once...and sold it. To me it seemed like such a limited area to quilt in, and I move faster than that when I quilt. Maybe for very small meandering it could work ok.

I use mine. I don't know how anyone could use it just a few time and get good with it. I practiced a lot and now it's easy as can be. I have two 6ft tables with my machine set in the middle. The tables fold up and easy to store and I keep the JF frame stored assembled. It cost under $150 and I can do end to end simple designs quick.
