Your thread storage is a wonderful inspiration and I will try it for my Weeks Dye Works Thread.
For my other threads I use bobbins, LoRain, a big original Anchor box for 400 flosses,
game boxes, Mon Cherry boxes and other praline boxes for small projects,
and handcrafted big panels :cartonages (100cm x 30 cm) with quilt fleece, thread fixes with elastic tape)
This is exactly how I want to organise my floss, but I am having a hard time finding the right ziplock bags as they are not available in my country. :(
