I decided to make my own diaper.
There’s no way I can go wrong since there are no specifications or even suggestions from NHRA
as to what qualifies an acceptable diaper.
The one I bought was a real joke using a nylon type material that easy to melt.
The straps were no better and above all the catches PLASTIC just like on a child’s nap sack.
The only positive thing that can be said about it was the fit was acceptable.
That did not take very much as there is only one end stitched to conform to the pan.


A yard of material at a local source at a cost of 9.00 that is much better quality and not nylon based. .
That is enough to material make three diapers. It is used on boats for seating.
To replace the plastic catches and nylon straps I ordered 6 canvas belts with D rings at 2.95 each from EBay.
So about 21.00 is the cost for all necessary materials.
I will take it to be stitched like the old one not sure of the cost.
Only part stitched to form is the front end which gets a pocket 7” deep and 9”wide.
The only place it need be stitched is to hold the straps to the diaper.
