I have posted a video highlighting the BERNINA #21 foot as the perfect way to add cording to the edge of a project. Here is the link to the video on my You Tube Channel. Be sure to subscribe to the channel when you get there.
I posted a new video on my You Tube channel yesterday showing how I use the BERNINA #2A foot to finish the edges of all my quilts before binding or to just keep them intact until I put the final finish on them. .
