These were a customer request, and who am I to say no!
I've made two larger designs which hold over 18 threads on each design, or these little mini ones you can buy extra tags for.
As they're made of acrylic, you can easily write the thread colour codes on the tags, a sharpie will do the trick! To remove, a bit of elbow grease and a wipe should do it (if it really won't budge some nail polish remover will likely do it, but this can damage the acrylic)
The mini organisers come in a set of 5 with a hand loop to keep them together (and attach to bags and other handy places!), there's also the option to add a few more to your collection. I can make these in any colour for you, just pop a note in the 'custom' box with the colours you'd like.
There's three designs, ring, star or conical flask (yes science!).
