Such an excellent idea! I love this, having the cone on top of my machine instead of behind it makes it so much easier to sew. I would highly recommend this to all who like to sew with cone threads.
Have you ever wanted to use a big cone of thread on your Singer Featherweight 221/222? Well this little tool has come in handy. True, you can use an alternative portable thread stand but this new product converts your existing spool pin and lives on top of your machine. I recently added this to Ruby, my 222, and it works wonderfully!
