For as long as I can remember, I have been sewing in my invisible zippers with a Singer Zipper foot that fits on my Janome sewing machine (below right). It bounces around a bit, but it’s ok. A few months ago I purchased this “Unique” brand package. A plastic Zipper Foot with a variety of shanks to fit any machine – supposedly useful for sewing in invisible zippers! Sorry… I found using my Singer Zipper foot to be more accurate.
I recently decided that it was time to splurge. After searching for a Janome Invisible Zipper foot – only to discover there was no such thing – I found a Janome Concealed Zipper foot… and I bought it, despite it’s silly name!
