Hi Penny.... I finally had a day off where I could work on your long stem roses. It only took me about 2 to 3 hours to make my first rose, since I wasn't sure what I was doing...
Found some wire that I had, and florist tape, so got my wire. Found some teeny tiny gold beads that I bought who knows how long ago, and didn't use for much (I seem to have that problem of buying things because I think they would be fun to play with, then don't use them for anything... LOL). I created my stamen using some regular dental floss, with the gold beads.. thought it turned out well, probably need to let the glue dry a bit more before I start to use it though. LOL
Was able to get my rose together with out too many problems, although I think I tend to use too much glue, but if I don't use much, it doesn't seem to hold. Do glue sticks get old and not work as well??? (I've had these for I don't know how many years... bought the glue and gun ages ago, but never really used it much either). But it also could have been that I didn't let my glue gun heat up enough before I started to use it.
Anyway.. on to my question....LOL
I resized the file to make a real life sized rose, and had all the parts selected to resize them proportionally, but the piece that is the green leafy thing that goes on the bottom, seems to be too large for the rose. It looks a lot larger than what you have on your roses. I'm not sure how much smaller to make it, so that it isn't so large. (Didn't want to make a bunch of roses trying to get that one part just the right size) I'm assuming that all the pieces in the file are proportional, which is why I resized them all together, but just wanted to make sure that is the case.
