About this machine
The SINGER Curvy 8770 is a computerized sewing machine with 225 built-in stitches, alphanumeric stitching and three StayBright LED lights. The exact product sheet distinguishes six fully automatic one-step buttonholes from a separate three-step infinite-length bar-tack buttonhole mode, while current SINGER support confirms the exact model in the computerized CB accessory group.
8770 is not a high-stitch-count version of 8763 by inference
SINGER's own exact product sheets establish the difference. The 8763 has 30 stitch patterns, while 8770 has 225 and adds alphanumeric stitching. A shared Curvy name and shared service manual explain their relationship, but the model-specific counts come from separate evidence.
Buttonhole terminology needs to stay precise
The 8770 product sheet lists six fully automatic one-step buttonholes and then a separate three-step infinite-length bar-tack buttonhole mode. Combining those into a generic 'seven one-step buttonholes' would change what the source actually says.
