BERNINA Binder Attachment for Unfolded Bias Tape #88 for tape widths of 28 mm (scant 1-1/8 in.) is ideal for bias-binding fabric edges. The unfolded tape is fed through the attached bias-tape feeder, positioned precisely on the fabric edge, and held in place securely until it is sewn. This produces neat, even edge bindings, with perfect corners and beautiful curves, on home furnishings, quilts, and items of clothing. After binding, the tape width will be 7 mm (0.275 in.) when using 28 mm tapes. Binder Attachment for Unfolded Bias Tape #88 must be used with matching Binder Foot #95 / 95C for perfect results. For 5.5 mm and 9 mm machines.
