Thanks, amti! I'm quite pleased with how this came out. I'm all about versatile pieces right now!
JerseyPearl -- the pearls were sold as 7.5-8.5mm, though I'd say the range is actually a bit larger than that - some are quite small, and some are quite plump. I don't have a good ruler for measuring pearls (nor will they cooperate very well at staying still!).
The tassels are here, but I'm still not sure how to put them together. I've also got lots of options...here are some photos.
The whole array of choices, shown with the lavender strand. Lighting is overhead LEDs. From left to right, small purple, small burgundy, large lilac, small lavender, large grey. All but the lavender are silk -- the lavender is synthetic and the strands are much thicker. it has a knotted band at the "neck" of the tassel.
I rigged the tassels the best I could with the strand, and also photographed them with a few options for "topper" beads. I didn't have a lot of time to stage these so please excuse all the odd lumps and the lighting. I also somehow didn't take a photo with the large lilac tassel, though I think I liked that color the least with the pearls (though I may wear it on a long sterling chain!)
