How to crochet bunting

We urgently need purple bunting, metres and metres of it! In order to raise money for the Northern Ireland Children's Hospice, Whitehead is staging "Operation Purple" during their annual Community Festival July 26 - August 10 2014.  Every business will wrap their shop in purple bunting to attract attention and raise vital funds for this important charity.  The bunting can be bought or handmade and since we run a wool shop we thought it would be perfect to use knitted and crocheted bunting. I've written a pattern and tutorial for anyone interested in helping us. We would be very grateful if you could send us even one piece. Our shop address is Lighthouse Yarns, c/o The Bank House, 12 Edward Road, Whitehead, BT38 9QB, Northern Ireland.

Thank you so much for helping!

Based on Double Knitting yarn and 4mm hook
(N.B. granny blocks are traditionally made from 3tr into each space.  However, in the triangle it's best to work 4tr into each space to avoid its curling up)

Foundation Ring: Work 4ch and join with a ss to form a ring

Round 1: 6ch (counts as 1tr, 3ch), [4tr into the ring, 3ch] twice, 3tr into the ring, join with ss into 3rd of 6ch (3 blocks and 3 corner spaces made)

Round 2: Ss into the next corner space, 6ch (counts as 1tr, 3ch), 4tr into the same sp, *1ch, [4tr, 3ch, 4tr] into next 3ch sp (corner made); rep from * once more, 1ch, 3tr into same sp as beg 6ch, join with ss into 3rd of 6ch

Round 3: Ss into the next corner space, 6ch (counts as 1tr, 3ch), 4tr into the same sp, *1ch, 4tr into the next 1ch sp, 1ch, [4tr, 3ch, 4tr] into the next corner sp, rep from * once more, 1ch, 4tr into the next 1ch sp, 1ch, 3tr into same sp as beg 6ch, join with ss into 3rd of 6ch

Work three more rounds in this way, working [4tr, 1ch] into each 1ch space along the sides and [4tr, 3ch, 4tr] into each corner space. 

Fasten off with a slip stitch into corner space.
