I have finally had my Rosewood Cowl pattern tested and tried, and it is live on Ravelry for $3.00 USD! The pattern has two downloads, one for the pattern proper and a step-by-step photo tutorial for the rosebuds, which are extremely easy to make, just difficult to demonstrate by words alone.
-210-340 yards DK or worsted weight yarn in main colour (testers' yardages varied wildly depending on the yarn weight used)
-60-100 yds yarn for roses (some testers used 40-50 yards), and about 40 yards for the leaves in DK, worsted, or aran
-gauge unimportant, just need flexible motifs. Testers used hooks from 4.00mm-5.5mm. I recommend using a slightly smaller hook for the rosebuds and leaves than you did for the cowl proper
-about 3-4 days to make. The pattern is beginner-friendly but interested enough to keep an experienced crocheter (like me!) challenged
