Machingers gloves for FMQ. Sorry to be bossy about it, but just try them and you'll be sold. Lightweight and breathable (I've accidentally gotten up from my machine and wandered around doing other things while still wearing them and not noticed!). When they start to get worn out you can just switch them to the other hand which gives you a new surface.
The woman who does instructional videos on Superior Threads' website wears Machingers, I've noticed.
Please just try them! (Unless you have large hands, try the S/M ones first).
