This summer I made 14 of these eye and stippling tool kit sets for my half of the Popper Clinic my fly fishing club presented. The other half of the clinic covered making balsa pencil poppers which another member was responsible for.

The diameters of the brass rods are 1/4", 3/16", 5/32", 1/8", and 3/32. The 1/4" will likely not be used much if at all.
The rods are from the Architecture Department of the local university book store. I made 14 in each diameter from one
3' rod. At about 2.25 inches in length, a handle for these isn't really needed since they are only going to be used to make
eyes. Kind of pricey, but it wouldn't be so much if spread around with a bunch of other tiers.
The handles on the others are balsa which I punched out and painted in a tan color for consistency and applied a coat of
two-ton epoxy as a clear coat after securing the needles in place with super glue.
The needles are
Prym Sewing 1.) Yarn Darners which come seven to a pack in sizes 14/18 *
2.) Tapestry Needles which come in a six pack in sizes 18/22 *
3.) 20 Sharps / Long in Size 7 *
I chose 7 needles from these packs which gave me a range of diameters suitable for what I believe most people might
need. But my personal set has some in-between sizes.
Except for the two smallest diameters which were ground from the points of the sharps, I cut the rest of the needles
below the eyes of the needles where the shape becomes round.
* Don't know whether the size is from smaller to larger or the other way around. Each pack is a $ or less. There is only
one of the largest Yarn Darner in a pack.
