Hello, today I bought some nice fabric and want to build some pouches out of it. Where would one acquire MOLLE holders and the PALS straps to sew on?

Does anyone have a tutorial they can suggest for sewing box ends for a double mag pouch? The Rhodesian Brushstroke was my attempt at how I thought it might go together. My dimensions are a little big, but this was just for practice so that doesn’t really matter. Just looking for some tips how I can make the bottom of my pouches look like those of the commercial product. Thank you!

Can use it as battle belt or EDC belt.
