Here is 'Quadrille' earrings in size 20 in 'Brilliant Sunset' thread by Yarnplayer. Below is them compared to a penny-so you get some idea how big they are. I really like this pattern for earrings. They are light enough you don't notice they are in(no chance of ripping holes out either) but large enough they don't fall out!
Below are a pair done in 'Roses' size 50 (also Marilee's thread) compared to a penny . I already had to make a replacement earring because I lost one. These are lighter still and I would put a back on the wires so you don't miss place one. After all it is a shame to put all that work into them and loose them!
