Yes, the darning foot does not come all the way down to the material. I have been stippling all of my quilts and if there is a problem with my getting any stitch, I check the following: Is the needle the correct one and installed properly, is the machine threaded correctly, I check my bobbin for the same, and I clean my machine to get rid of any lint by the feed dogs, etc. I have been quilting for over 10 years and sometimes I still have to check those items again. You might do well by getting a Singer foot.
