This is the 1st time I'm asking this website a question.. But what do the pomegranates in blue, purple and scarlet material look like? Are they actual pomegranates (which as far as I know, are red... Wrapped up in fabric?
I believe the OP is referring to the pomegranates that form the hem of the me'il [robe] of the Kohen Gadhol [high priest]. See Exodus 28:33-34 and 39:24-26.
My understanding of these verses is the simplest, contextual meaning of what they looked like would be tassels: the blue, purple, and crimson threads that form the robe gathered and tied together. A tassel/knot with the loose ends hanging out visually resembles a pomegranate (crown pointing down).
You can actually see a reconstructed example at this website (scroll to the middle of the page) [warning: I am not endorsing this organization, their message, or their accuracy in anything except this particular example of the pomegranate tassels, which I found surprisingly well-done. The rest, not so much]: http://www.mishkanministries.org/highpriest.php
