Cable Pattern Plight

[jskjerven]

I'm working on a sweater pattern from Better Homes and Gardens, called lace & cables cardingan. It's a lovely sweater but a little advanced so I'm struggling. I've mastered the lace pattern, and most of the cable pattern. There's one stitch that evades me... In row 7 of the cable, the pattern calls for Tw10B.

Have any of you heard of this?

Thanks
Janet
