• did consider coroplast but i never see any about and isn't it only strong in the one direction? in the other direction it will fold, right?. Not necessarily the biggest problem but I dunno, seems best not to have that.

  • I usually cut it to fit the entire inner circumference with the 'grain' running along the length of the bag, fold to suit and sometimes anchor it, sometimes not.
    I've used it in multiple Carradice bags, never been a problem.
