I have found for those with arthritis a curved needle works well. Any other suggestions?

I just found twin pointed needles (eye in the middle of the shaft). I love 'em! There's a learning curve as the eye is a weak part and I've broken two needles.
They have made my stab stitching so much easier for me that I have ordered a box. Considering it a reasonable expense.

Curved needls are the best if you are hand basting the quilt.

I also find curved needles work better on small projects.
