I used these patterns to make my Butterfly Scarf, and matching hat (when I finish it!).  For the scarf I made 2 small, 2 medium, and 1 large butterfly.

You could make these using any scrap yarn and matching hook size.

Small Butterfly

This one is worked in rows.

Tip: To save weaving in ends, measure  5m of the main (wing) colour of yarn and start crocheting from the middle (i.e. leave a really long tail).  Then when you move on to the second side, use up the tail instead of starting with a new length of yarn.

Start with the body colour:

Ch3, switch to wing colour.

R1: ch2 (counts as dc), dc in 3^rd ch, sc, 2dc (5sts)

R2: ch2 (counts as dc), turn, dc in same st, (2dc), sl-st, (2sc), (2sc) (9sts)

Fasten off this side.  Pick up the body colour, ch1.

R3: sc in each of the foundation chains (3sts), change to wing colour

R4: repat row 1 (5sts)

R5: ch1 (counts as sc), turn, sc in same st, (2sc), sl-st, (2dc), (2dc) (9 sts)

To finish, weave in the wing colour ends.  Weave the body colour ends to the top of the butterfly body and knot together to make a head and antennae.

Medium Butterfly

This one is worked in the round.  You can make a 3 coloured version by changing colour after R1 if you like.

Start with a magic circle (or a ring of 4 ch if you prefer) in the colour of the inner wings.

R1: 9dc into magic circle, sl st to join (9sts)

R2: ch1, sc in same st, *3dc, sc, repeat from * 3 more times, sc in same st as just worked, sl-st to join (change to wing tip colour if you like) (18sts)

R3: ch1 (counts as sc), [(2sc),(2dc, ch2, sl-st in 2^nd ch from hook, 2dc), (2sc)], sl-st, *sc, (4dc), sc, sl st, repeat from *, repeat everything inside[],sc, sk 1 st, sl-st to join.

Weave in all ends.  Make a chain long enough to wrap around the body, and knot to secure.  Use the tails as antennae!

Large Butterfly

I used this lovely pattern from The Left Side of Crochet:

I started with white, switched to lilac for round 2, and used grey for round 3.  I also made a chain for the body as, similarly to my medium butterfly, I thought tying around just the plain yarn was not thick enough.  For the antennae I drew the starting tail through and knotted both together, and trimmed to length.

I hope you have fun making this quick little projects! What will you sew yours on to?
