Four leaves and four lengths
On this page10
The group has four leaves and they span two orders of magnitude
A stitch marker is a ring of a few millimeters. A cable needle runs four to five inches. Between them sit a tapestry needle and a gauge swatch tag.
The stitch marker is the smallest storage problem on this shelf
Light, small, and it will go through any gap. 13 of this group’s 253 containers hold less than 15 mL and 24 hold less than 30, which is where the marker belongs.
And its real requirement is the closure rather than the body
A ring that weighs almost nothing escapes a lid that is merely resting on the rim. A continuous thread lid that is actually turned down is the difference between a sorted set and a loose handful.
A tapestry needle is blunt and short
Roughly one and a half to two and a half inches, and blunt, so it does not work its way into a wall or a liner the way a sharp does.
A cable needle is the longest thing in the group
Four to five inches, often with a bend or a crook in the middle. Of the 237 rows on this shelf that record a height, 21 reach four inches and 14 reach five, and the tallest is 6.745.
Which puts it at the thin end of the shelf
A long cable needle is close to the point where the shelf stops having an answer, and the three rows this group has that the shared shelf does not are exactly the narrow tall shape it wants.
The gauge swatch tag is a flat object and a different problem again
A tag is read, not poured. It wants to lie flat and stay in order, which argues for a wide shallow container and against anything the hand cannot reach into.
So the group splits the same way the embroidery group does
Two leaves want depth and two want a floor. Which is a property of a group of tools rather than a group of contents, and it is why a single container recommendation would be wrong here.
None of the four is a wool product
Part 300 governs the fiber content and origin label on a wool product. A needle, a marker and a tag are not wool products and nothing on these pages says the part reaches them.
