Just want to do a quick check to see if my parnell knot attempts were done correctly - please let me know if it looks off. First two pics are one side of the racquet at different angles and the last two are the other side of the racquet. Thanks!
Looks pretty good to me. That's pretty much the only knot I use.
Keep in mind, the FIRST loop is the one that holds the tension so take care tightening that one. The SECOND loop simply finishes off the knot and allows you to seat the tail in an aesthetic manner. It is not necessary to over-tighten the second loop. Actually, I usually tighten the second loop by hand.
