hi JGidget! thanks for asking!
I didn't have a pattern. there are different ways to do basketweave. mine is a stockinette/reverse stockinette checkerboard. I lost my knitting notebook early this year, but lemme see if I can remember how I did it:
cast on 25 stitches
4 row garter border:
row 1 (RS) : slip 1st stitch purlwise, then K to end
2nd through 4th rows: same as row 1
first "row" of garter edge and basketweave checkerboard squares:
slip all 1st stitches purlwise
row 5 (RS): K10 P5 K10
row 6 (WS): K5 P5 K5 P5 K5
row 7 (RS): repeat row 5
row 8 (WS): repeat row 6
second "row" of garter edge and basketweave checkerboard squares:
slip all 1st stitches purlwise
row 9 (RS): K5 P5 K5 P5 K5
row 10: (WS): K10 P5 K10
row 11 (RS): repeat row 9
row 12 (WS): repeat row 10
repeat these 2 "rows" until scarf is desired length.
finish with 4 row garter border.
HTH and hope it's correct.
