I just saw this tute: http://www.quiltingboard.com/t-57715-1.htm

I love it and I want to make a baby quilt but I can't do the top quilting. I only have a regular sewing machine.
Can I still make a pinwheel quilt without doing any top stitching?

You can do top stitching on a regular sewing machine, so I'm not sure what your question is.

Is your problem that you don't have an embroidery foot for free motion quilting? It would not be as stunning, but you could tie the quilt.

You could still do SID, just use a stilleto to hold down the loose pinwheel edges :D:D:D

I quilt all my quilts on a regular home sewing machine. In fact, I use a vintage sewing machine with a small harp. It can be done. It is easier with a thin batting like warm and natural. Do not use a high loft batting unless you plan to tie the quilt.

Many, many quilters do all their sewing on a "regular" sewing machine. Sometimes it takes a bit of forethought, a bit of ingenuity and sometimes a bit of luck, but it can be done!

go for it you just need a straight stitch to do that

I have an XL3022 Brother machine and it's 14 years old. The feed dog can't be lowered. I have a walking foot on order through Amazon.com though. I've only made a table runner and placemats, both of which I stitched in the ditch. Only batting I've used so far is low loft.
I'm so inexperienced at all this.

If your concern is the 3-D pinwheels, just don't quilt over them. (just around them.) Go by the distance give on the batting, as to how much (maximum) space to put between the stitches.

You don't need to lower the feed dogs for top stitching and my older brother has a plastic piece that sits over the feed dogs to allow you to use as if they were lowered
