This afghan calls for 6 skeins of LION BRAND Homespun Bulky yarn (their own chart describes #5 yarn as “chunky” and #6 yarn as “bulky”, but the yarn itself is a #5 and called Bulky). It comes in 185 yard skeins.
The gauge given in instructions cannot be expressed in the format available in the Ravelry system; I divided it to match the largest (4”) choice, but here is the accurate gauge information:
2 Petals and 2 sc = 6” (15 cm)
1 Petal = 4 tr in the indicated stitch
In addition to the K-10.5 hook, you will need a yarn needle.
