12 Glow in the Dark 3-D printed stitch markers!
 
Guys, how stinking cool are these?! Each stitch marker is printed on our home 3D printer. These are made of a hard plastic that freaking glows in the dark!  As with most glowing things, they need to be "charged" in the light or outside to give off their best glow when it's dark. 
 
Small - fits up to a 3.25 mm, US 3 needle
Medium - fits up to a 5.5 mm, US 9 needle.  
Large - fits up to a 10 mm, US 15 needle
 
I've been using them and found no issues with snagging.
