GSG is based on Half Persian 3-1 Sheet 6. GSG is basically two rows of Half Persian 3-1 Sheet 6; if you know how to make that, you can make GSG with little additional difficulty. Since there are fewer rings to stabilize each row, the beginning of the weave can get tricky if the rings get out of whack. You can make a wider patch of Half Persian 3-1 Sheet 6 to start with, then change to 2-ring rows for an easier start to GSG.
GSG can be made with smaller AR's than Half Persian 3-1 Sheet 6; down to about 4.2. Larger AR's will simply make the chain more open and easier to weave. 20awg 1/8", 18swg 3/16" and 16swg 1/4" rings work at the tight end of the scale.
Metric sizes - approximately 0.8mm wire/3mm ID; 1.2mm wire/4.8mm ID; and 1.6mm wire/6.5mm ID.
Note: If you use the above ring sizes you cannot use preclosed rings - instead you'll need to weave one ring at a time. If you use a higher AR you can use preclosed rings.
New rings are gold, old rings are steel.
Step 2: Pass a ring up through the eye. It should go above the open ring from the previous step.
Step 3: Preclose 2 rings and put them on an open ring. Pass the open ring down through the eye from the previous steps. Arrange the preclosed rings to form another () eye.
Step 4: Pass an open ring up through the eye from the previous step, and up and around the eye from Step 1.
Step 5: Repeat Steps 3 and 4 until the chain is the desired length.
