Knitting - neat 'rolled edge' Scarf

This edging isn't exactly a rolled edge, but gives the appearance of one ............

Edging:

Right Side row: 

Sl1 kw, K1tbl, P1 - continue in your chosen pattern until 3 sts before end of row - P1, K1tbl, K1 tbl

Wrong Side row:

P1, P1, K1tbl - knit chosen pattern to 3 sts before end of this row - K1, P1, K1tbl

Abbreviations:

S = slip

KW = knitwise

K = knit

P = purl 

tbl = through back of loop

Note for Scarf Pattern:
For the above scarf, I used double knitting yarn, and cast on 30 sts. and used alternate bands of garter and moss stitch (plus the single ribbing at the beginning).
