Aspect Ratio for Half Persian
by Kylie Jones
This weave makes a slinky snake like chain. It is a perfect chain to wear on its own or to use to highlight an original front pendant design.
Instructions
Aspect ratio is a calculation of the relationship between the size of the wire used to make the jump ring and the size of the mandrel used to make the ring. It is a number that tells you about the amount of space inside a jump ring.Aspect ratio AR = Inner diameter of the jump ring divided by wire diameter (wire size). Example. 20g AWG (0.8mm) ID 5/32" (4.1mm)jump rings. AR = 4.1 รท0.8 =5.1For more information about aspect ratio please see my tool tips.
To keep the slinky softness of this chain the aspect ratio is important. The smaller the aspect ratio the more rigid the chain becomes.In the first example with the AR of 4.5 the chain is so rigid it can be shaped, this hard taut pattern can be good for earrings. The larger the aspect ratio is the less defined the pattern becomes, which gives a much more lacy look.I think around 5 is perfect for this weave as it is tight enough to keep the snake like tension but loose enough to feel slinky on your body. The AR you choose will depend on what you want to achieve in your design.
