Thanks for the offer, Marty, but problem solved. My ds just called me and had them in his hands and is ready to pay at a WalMart way north of here. He's on his way home from visiting friends. Something like .97 for a package of four. Wish my Viking's bobbins were so cheap. They're over a dollar a piece! I've bought them online cheaper though.
Thanks, everyone! Good info, Laura. We tend to take our little bobbins for granted, don't we, and they're so very important!
I made pincushions (like the one I made myself except not for the wrist) for them today and tomorrow the gifts get wrapped and wait for the parents to pick them up. It's been fun.
