I won't have any crochet time tonight, and probably none tomorrow either, but it's the monthly Craft At The Library meeting on Friday so I may be able to try it then.
For now, after a mini rose, here is a tiny rose
The original pattern specified worsted/aran wool with a 3.5mm hook, which is an unusual combination; I used the yarn I have, which is 4-ply, and which I usually work with a 4mm hook. So I tried that first, and found that the rose was very loose and lacked definition. Then I tried again with a 2.5mm hook, and the rose above was the result - much crisper in line. Here is a pic showing them both (I didn't do leaves for the larger ones) - exact same pattern, exact same yarn, the only difference was hook size!
And to give you an idea of size, here are the mini and the tiny rose with a ruler:
