My "P" Hook Infinity Scarf Pattern I invented:
Using 2 strands together- Chain 102 chains, join, being careful not to twist chain.
Row 1: SC around into each chain, join into 1st SC, CH-2, do not turn.
Row 2: HDC around into each SC below, slip stitch to join, ch-1, do not turn.
Row 3: SC in back stitch of every HDC below, around, slip stitch to join, ch-2, don't turn.
Row 4: HDC in SC around, join, ch-1, don't turn- ever.
Row 5: SC in back stitch around, join with slip-stitch, ch-2.
Row 6: HDC around, slip-stitch to join, CH 1.
Row 7: SC in both loops of HDC. This is the ending row, on one side of the infinity scarf. Join, finish off, weave ends in.
Row 8: Turn your infinity scarf, so opposite beginning end is facing you, SC in both stitches of SC around, join, finish off, weave in ends.
FINISHING TOUCHES:

On both edges, do a slip stitch in each stitch around, to give it a more "finished" look and nice edging.
Turn scarf into a figure 8, put over head, arrange how you want it to go, on your bodice, with inside a coat or outside a coat or sweater.
