A quick post , hopefully another will follow later today...
Crochet Rose Tutorial
DK weight yarn (I used Rowan's DK Handknit Cotton)
Crochet Hook size 3.75mm
Tapestry needle for sewing up
You are going to chain 40 stitches. Each rose petal will be formed by 5 crochet stitches: SC,DC,TC,DC,SC, in that order. You will work these 5 stitches into every alternate chain stitch, ie skip a chain stitch between petals.
