I have no idea what the "proper" name for this is.
My idea of a "String" is where you complete the 1st side of more than one ring, close the 1st ring then complete the 2nd side and close the rest of the rings in sequence.
It is a little fiddly but not difficult to do.
This bow is made using this technique.
We are going to make something a little simpler.
Snowflake
Rings 1-2: 3 ds, p, 3 ds, place marker, 4 ds, p, 4 ds, draw thread through to marker leaving both loops on hook, 3 ds, p, 3 ds, close ring.
Rings 3-10: 3 ds, jp, 3 ds, place marker, 4 ds, p, 4 ds, draw thread through to marker leaving both loops on hook, 3 ds, p, 3 ds, close ring.
Rings 11-12: 3 ds, jp, 3 ds, place marker, 4 ds, p, 4 ds,draw thread through to marker leaving both loops on hook, 3 ds, jpto ring 2, 3 ds, close ring.
Fasten off, tie ends together and sew them in.
1. Work 3 ds, p, 3 ds. Place a piece of contrasting yarn over
the yarn you are working with, sliding it up close to the last ds.
This is the 1st side of ring 2.
If you want to be really brave, try making a string of three rings in one
go.
Rings 1-3: 3 ds, p, 3 ds, place marker, 3 ds, p, 3 ds, place marker,
4 ds, p, 4 ds, draw thread through to marker leaving both loops on hook,
3 ds, p, 3 ds, draw thread through to marker leaving both loops on hook,
3 ds, p, 3 ds, close ring.
You should know enough now to be able to make this into another snowflake
if you would like to.
