knot for t-top canvas lashing

I’m about the relash my life jacket bag to my t-top and I interested in some opinions on what knot to use at the end. Once I weave the cord around and bring it together, I need to knot the two ends of the cord tightly while maintaining tension on both ends. What would you use?

I usually just use a slip knot on one end, feed the other end thru, pull tight and tie two or three half hitches.
