Gridfinity blocks to organize sewing thread spools.

The spool blocks are based around the Günterman 100m/250m/500m spools, most other brands I had laying around are similar diameters but slightly shorter and still fit.

The bobbin blocks fit ø 20mm x 11.5 mm bobbins for Janome machines, if your machine takes a larger bobbin it probably won't fit.

• 6 x ø 20mm spools (100 meters) in a 2x3 block
• 2 x ø 30mm spools (500 meters, smaller 250 meter spools also fit well) in a 1x3
• 3 bobbins in a 1x1 block.
• 9 bobbins in a 1x2 block. 50% denser than the 1x1 block but harder to remove from, so I only use this one for empties.
