Here are three of the adjustable necklaces that I made from my latest bead show excursion.
One with a spring green pendant:
One with a medium blue pendant
And one with a maroon pendant.
They are all about 24-26 inches long and can be shortened to match either your clothing or your size. They are very comfortable to wear.
I have one more pendant, a red heart, that I have but I ran out of beads that I liked to go with the red. Reds are very hard to match but I found some nice shiny ceramic round beads. However, I ran out of black beads to go with them. Go figure. Those are fairly easy to find. I just have to do it!
