After owning my Singer Athena for about 20 years, I tried the blind hem foot, previously just used zigzag foot. Oh my goodness what a difference that foot made, what took me so long? Another feature, used the double needle that came with the machine on a knit top my daughter wanted fixed. The machine had a switch to flip when using the double needle, think it set the tension, and well....it made the most beautiful hem stitch for the knit.
I have a Pfaff now, 9years, making the effort to use all the features in the book. Wow so many cool things to dress up projects. The feature that I like the most, it wasn't even on my list, is the needle down button...LOVE IT!!!! Another foot that I purchased with it is the stitch in the ditch foot, works great. Wish I had purchased a cording foot, like to make artsy things at Christmas time.
