Unwind one hank of A.
Sew one end of yarn to top of shade. Thread blunt needle with a strand of B.
Gently wrap A once around shade. Continue wrapping and as you wrap, whipstitch top edge of this second wrap to the lower edge of the first wrap.
Continue in this way until shade is covered.
Trim end of A and, with sewing needle and thread, sew yarn end to shade.
Cut a length of B long enough to encircle top of shade + 4 in. (10 cm).
Cut a length of A twice the circumference of top of shade. Draw B through A to gather B so that the resulting circle is the circumference of top of shade.
With B, whip stitch trim to top of shade, wrapping B over trim in places to make 'poufs' of yarn.
Lower Edge Trim
Make same as top trim.
