The GFP Bobbin Hook

A simple paper clip twisted around your bobbin and you've got yourself a virtually free bobbin hook similar to Mitch's Bobbin Whirler and allows you to make dubbing loops without the need for a second tool.

Here's a shot of the hook in action, on a test hook, but you can see how right at the bobbin tip the hook has the dubbing loop and it's all set and ready to wrap around the hook.

The few minutes it takes you to make this is worth it since you'll never be searching for your dubbing twister or having your bobbin get in the way while spinning it up!

UPDATE: Here's a short video of it in action.
