I have seen "Idoit's Delight" or King's Link chains done with
graduated sizes of jump rings so the chain is considerably finer
at the ends than it is in the centre of the necklace. Are there
any guidelines or is this discovered by trial and error?
The easiest way I know is this:
1. Divide the chain into 1 inch sections, the largest diameter
links & wire size would be the 2 center sections (assuming an
even length chain, 16, 18 in. etc).
2. Make the next section on both sides of the center section
.05mm smaller links of the same size wire as the center 2
3. Make the next section on each size the same size link as the
previous section but use the next smaller size wire.
4. Continue this scheme until you've reached the length you
If you'd like, you can vary the length of each of the sections
(they should all be the same, however). This results in a chain
with almost imperceptible taper. Making a larger change in link
diameter or changing both link diameter & wire size at the same
time results in an obvious 'bump' in the chain.
16 in chain + 16 1in sections Center 2 sections, 5mm 16ga; next
section each side of center, 5mm 18ga; next section, 4.5mm 18ga;
next section, 4.5mm 20ga; next section 4mm 20 ga; next, 4mm 22ga
next, 3.5mm 22ga; next 3.5mm 24ga.
While the above dimensions might not make an appealing chain, it
does serve to illustrate a graduated chain technique.
The important thing to remember is NEVER change the link size &
wire size at the same time!
