I've been making a lot of circular motifs, and finding the sliding ring/magic loop technique has become my favourite method to start in the round. Not being happy with the photos I posted last time (I over did the saturation) I decided to have a re-do.
Step 1: wind yarn around finger, with end away from you. Don't have it too tight, as you need to fit the hook under (step 2)
Step 3: bring yarn through both loops
Step 4: remove from finger
Step 5: chain (I'm using US dc, so 3 chains. US tr would require 4 etc)
Step 6: complete 1st row (my pattern is for 23dc + 3ch for 24 stitches)
Slip Stitch into top of chain row and you are ready to start 2nd row.
