i would like to share a tutorial for a soap bag that I made that works quite well for /out/ adventures. it basically consists of 2 layers of nonwoven hydrophobic cloth, which can be cut out of a surgical mask or garden insulation. it allows the soap to dry without wetting, leading to no soggy soap in the morning, and serves a similar purpose to on-market items such as the matador soap bag. let me know if there's any additions you think would be good, and it's a nice way to use solid soap which is much more packable.
