I don't know exactly what clear embellishments you are talking about, but if they are acrylic or acetate, like the Heidi Swapp ghost shapes, you should try alcohol inks! They are a lot of fun. I haven't used them on any los yet, but I have been practicing with them. They are awesome.
There are a few videos on this site that show how to use them too.
I love the ghost shapes from Heidi Swapp . I have used alcohol inks on them, as well as paint. If you paint on them, make sure you paint on the side that will go against the paper. Also, stickles don't stick too well on them, unfortunately. I got some acrylic paint with sparkles in it. You can also ink or paint the edges and leave the middle clear. HTH! I'll see if I can find my LOs where I used them.
If the clear items are acrylic or plastic I just saw a really neat idea from Kristina Werner (starofmay) on You Tube (just search her name)
She use versamark embossing ink on a stamp and pressed her clear button on the stamp, then poured embossing powder over the inked button and heat set it......it is a great effect! You could do this with any clear acrylic piece
The Glimmer Mist does dry eventually. It just takes a long time. I kinda oversprayed mine so I got little beads that dried into circles with clear centers. In the end, it looked really nice. I've also used acrylic paint pens around the edges, and stamped with StazOn inks.
