Bobbin & spool fit guide
The Sew Stack bobbin tray holds class 15 (A-style), class 66, L-style and M-style bobbins; the spool tray is built around the small and medium spools quilters use most. Here's what we and our customers have confirmed.

| L-style | Yes | Confirmed by us. |
| M-style / M-class (longarm) | Yes | Customers store longarm M bobbins in one tray and domestic in another. |

Each tray holds 40 bobbins on edge, in 10 channels of 4. Bobbins seat on molded dimples that fit the center hole.
Thread spools
Each spool tray holds 16 small or medium spools on pegs, including Aurifil, Mettler, Gütermann and Sulky. Spools up to about 1⅜" (35 mm) across fit side by side; with another tray or a lid on top there's room for spools up to about 2½" (64 mm) tall. Large cones and king spools are too big.
