I’m always on the lookout for great handicraft projects and we just finished a great one! We made parachord bracelets from a kit I picked up a Walmart (you can also find paracord and buckles at most craft stores). My 6yo was able to do the knots on her own (she needed some help geting the buckles attached). My 11 and 8yos just needed help with the finishing part. The 3yo made one with my DH’s help.
Here are some instructions…you don’t need a “weaving appartatus”, our plans had them tape it down which we didn’t even do (we were on vacation): https://www.operationgratitude.com/wp-content/uploads/2011/04/HowtoMakeaParacordSurvivalBracelet1.pdf
