Griffin Jewelry Silk on Spools
The Griffin Jewelry Silk is a high quality filament silk from Germany. This silk is a standard beading silk that has be made for many years. Griffin has been around since 1866. The thread quality, diameter and colors are incredibly consistent. It shows the high quality standard levels at the factory where this thread is made. The silk on the spool is a 3-ply cord with a left twist made from 100% natural silk.
I currently carry two sizes of the Griffin Jewelry Silk on spools > Marion Jewels in Fiber Online Store
6/F Ø - 0.35 mm - 65 meters per spool
8/FFF Ø - 0.42 mm - 40 meters per spool
Griffin 100% Natural Silk on Cards
The silk on the card is the same silk as what's on the spools, but it is twisted into a cordon, a 2-ply twist with a needle attached at the folded end. One of the drawback is the short length of the card, only 2 meter long making it difficult to use this silk for longer necklaces, crocheted necklaces and any other project requiring longer length of silk.
So yes one of the solution if you need silk with a needle attached at the end like the one that comes on cards is to make your own. To make your own 2-ply silk cordon (re-twisted 2-ply cord) > Check this post on making 2-ply twisted cord with Griffin Jewelry Silk
Here is a chart that compares diameter sizes between the silk on spool and cards, plus 2 and 3-ply cordons made with the silk on spools. It is a handy reference for anyone working with this silk. Diameter sizes are approximate and based on information provided by Griffin.
I hope this will help anyone with questions about how these two silk products compare. It will certainly make a handy reference when I am next asked questions about how to compare Griffin Jewelry Silk and Griffin Silk on Cards! - Marion
