I've got a quick little tidbit for you that may come in handy, and might save your thumbs too!
If you don't have the basting pins that are curved (I wish I had those) you can try this trick to help you out when you baste your quilt.
(Let me apologize ahead of time for the poor photos. It gets dark now at like 5:30 so taking pictures is a pain. Boo!!)
Grab your quilt, your pins, and a spoon. :)
Place your pin in your quilt and set the spoon under the pin using either the tip of the spoon, or the side of the spoon....find what is most comfortable for you.
Then use the spoon to help you close the pin.
Your thumbs will thank you for it! :)
