I have the Janome 6600 with built in walking foot and use it for just about everything as well. The add on ones are a bit more clunky, but are still great for straight line quilting the sandwich to help avoid puckers.

I quit using my walking foot becauseit was eating fabric. I used it for stitch-in-the-ditch quilting, and adding binding. But it worked so well for those things that I left it on. Big mistake! I also stitched in reverse with it, which I have since found out, is a big NO-NO. Not sure why, as it worked perfectly in reverse. It got very frustrating when the fabric wouldn't move through, and time after time I got big wads of fabric and big knots. So I took it off and put it in the drawer. The next time I need it for binding I will attempt to use it again.

I have a janome 11000 and I only use my walking foot for binding and quilting straight lines. I have attended a paper piecing class and someone was using her walking foot, she said she uses it for everything. I guess whatever a person is comfortable with.

I use my walking foot on large quilting projects. Have never used it on small pieces. Interesting to read the responses.

Thanks Buckeye Rose. It's good to know I'm not the only one who uses it for everything. Even on my original 5042 Janome, I left the walking foot on and it was one that had to be attached.

I have a Janome 7700 and a 1/4" walking foot. I do use it for piecing sometimes but where it shines, to me, is sewing on the binding. It feeds the fabric without shifting and keeps me on the 'straight and narrow' for my seams. That black guide takes a little getting used to for regular piecing but I hate changing feet so I usually just suffer through. The regular walking foot (accufeed as they are called on the 7700) is wonderful for straight line quilting and I would never use the 1/4" accufeed for that.

I don't usually use the walking foot to piece, but I do with flannel.

Mkotch: That's a really good idea because flannel is forever shifting. Next time I am going to try it.

I generally use my walking foot for the actual quilting, and use the 1/4" foot when sewing pieces together, especially the smaller 1.5" or 2" pieces. Hope this helps.

Seldom use my walking foot anymore
 

Just finished another quilt that required a walking foot. Didn't want to go through the hassle of installing the walking foot for this particular project so attached my darning foot instead. Worked beautifully!! Am doubting that I'll ever use the walking foot again!!
