Middle four, 8-foot strands of 1/8” cotton, dacron or nylon braided cord.
Temporarily seize the four strands with a slipped Constrictor knot (Ashley’s #1250), sail thread, whipping twine or dental floss is excellent, about 2” to one side of the middle.
Separate the strands into two groups (A,B & C,D).
Cross B to the right over C.
Pass A behind C & B, then back over B, and down beside C.
Likewise, pass D behind B & A, then back over A, and down beside B.
Work the leads and snug the knot up against the constrictor knot to get a uniform and reasonably tight sinnet.
Work the sinnet to about four inches long, passing through the middle of the four strands and ending up roughly centered in the strands.
Form a bight as the bell clapper loop. Permanently seize the two ends of the sinnet tightly together using a doubled Constrictor knot (Ashley’s #1252). Remove the slipped Constrictor temporary seizing.
Size the bight as you like; allow about 1/2” overage on each side for the following Matthew Walker.Upon completion, loosen the 8 strands back to the permanent seizing and arrange as symmetrically as possible.Hint: Insert a 3/4” strand of the same 1/8” cordage to help keep the 8 strands rounded an make the following Matthew Walker work up neater.
