Uber fine curved needles!!! For beading but also for hard to get to places where the subject has little or no flex.
These needles are used by couture houses that produced highly embellished garments and they are quite handy for when your subject is 'standing'.
They came to my attention when one of my students bought some to class... she'd been working at top London couture house Ralph and Russo, where they make the most sparliest beadiest gowns for many A-listers. Well now you can get those needles here and channel that sparkle!
