Here's a cozy yet speedy project: Cut 12 pieces of bulky-weight yarn to about 1 1/2 times the desired length of the final scarf. (We used 140-inch pieces to make an 86-inch scarf.) Divide yarn into 4 bunches of 3 strands each. Tie 2 bunches together with a square knot, leaving 6 inches of fringe at end; repeat with remaining bunches. Pin the knots to a piece of foam board. Knot inner 2 bunches of yarn together, spacing knot about 1 inch from existing knots, then knot left and right bunches together. Alternate knotting the inner bunches and the left and right ones, spacing knots evenly apart, until about 6 inches of yarn remain on the end. Finish so that final knots mirror opposite end, and trim to even the ends.
