These lights look terrific on my Christmas Tree which is hung entirely with my own home-made decorations. The idea for this pattern is not original, it came from many Pinterest posts however this pattern is my own.

Make 6 to 12 in different colours. A set of six lights will measure approximately two metres when chained together.
Using coloured yarn, cast on 4 sts
1st row: Kfb to end. (8sts)
Starting with a purl row, stst 3 rows.
4th row: (k1, m1, k1) to end. (12sts)
Stst 3 rows.
8th row: (k1, m1, k1) to end. (18sts)

12th row: (k1, m1, k1) to end. (27sts)
Stst 7 rows.
Next row: (k2tog) to last st, k1. (14sts)

Break off colour
Change colour to white and stst 4 rows.

B&T tightly.
Make up
Over sew row ends using matching yarn and leaving a gap at the centre. Stuff firmly and sew closed.
Finishing
Using white and 4mm crochet hook, chain 50, dc in top of first light, chain 50 and dc into top of next light. Continue as before until all lifhts have been attached. Chain 50, cut yarn and pull through. Sew yarn ends into chain.
Make more or less lights and make the chain in between longer or shorter as desired.
