How to Avoid a Twisted Picot
A proper join made at a picot should show two parallel thread of the picot and not twisted like an 'X'.
The twisted picot can be avoided by way of making what is sometimes called a Folded Join. I hope the few steps shown below will be able to explain how to make the folded join to avoid the twisted picot.
When you have reached the point to make the join, turn over the piece so that the reverse side is now facing up and the first ring is now on the left side. The picot is now in the correct position to make a join, but we are not there yet!
Fold part of the work over so that the front side of the first ring is facing up. Bring the picot to be joined close to the core thread of the ring being worked. Make a join through this picot as usual.
Straighten out the last ring so that it is in the correct position and slowly close the ring. You have now completed making a join and avoiding a twisted picot.
Below are a few more pictorial examples of making a folded join.
a) Above left - the last ring in the clover is to be joined to the first ring of the first clover on the right;
b) Above right - the motif is turned over;
c) Right - the motif is folded over to bring the picot to be joined to the correct position for making the join.
d) Left - the motif with the join made.
I noticed that I need to make this type of join if the joining picot is on the right side of the ring/chain being worked.
