I'm liking the Basket stitch and the Double Moss stitch. they both give a nice textured look. There are a couple other textured stitch patterns that I really like, but both of these are simple enough that I quickly get into a rhythm. Once I find my rhythm with each of these stitches, it's as easy as garter stitch mostly and I stop having to pay attention to what I'm doing. Admittedly, if I get interrupted I have to go back and count where I am, but again both of these are simple enough that finding where I left off in the stitch pattern is very easy.
Basket Stitch is the following pattern:
multiples of 6 sts.
Row 1: Knit
Row 2: Purl
Row 3:*K1, P4, K1, rep from * to end
Row 4:*P1, K4, P1, rep from * to end
Row 5: As row 3
Row 6: As row 4
Row 7: K
Row 8: P
Row 9: *P2, K2, P2, rep from * to end
Row 10:*K2, P2, K2 rep from * to end
Row 11: As row 9
Row 12: As row 10
Repeat these 12 rows.
I know it looks like a lot, but it's a really rhythmic stitch and once you get to working it, it just flies off my fingers.
And the Double Moss is:
Multiples of 4 plus 2
Row 1: *K2, P2 rep from * to last 2 stitches K2
Row 2: *P2, K2 rep from * to last 2 stitches K2
Row 3: As row 2
Row 4: As row 3
Repeat these 4 rows.
I hope this helps.
