I started a thread about mine a couple of years ago- you should be able to search it up.
1 1/2" polyester seat belt webbing is just about ideal. Start and end it with the double loop sliders- I bought my stuff from Strapworks- but beware, they did NOT send me the continuous item I ordered....it was taped 1/2 way thru the roll. Fortunately, I had enough to do the job.
First run is just a spiral- run that crosses that is where all the weaving happens. Leave a little extra length on the spiral in case you have to loosen it a little as you near the end of your weave....it tightens as you go. You can tighten at the end, no problem. The seat belt webbing does not stretch noticeably- ends up tight as a drum and very stable. It is also extremely durable. You want to get right up to the end and into each corner to avoid an entrapment risk. Not hard, just do your measurements and order your webbing in an appropriate width to ensure it leaves a small enough gap to eliminate holes a foot could get wedged into. You will not have to worry about anything between the weave- it is tight and stable when complete.
Let me know if you need pics or have ?'s. It's a great way to go- you will love it.
