I look at handicrafts also as “life skills”. So anything our sons will need to know how to do on their own for the amount of time they live on their own before they get married, and then things they will need to be a provider and protector of their home. My son is 2 but I think when we begin handicrafts initially they will be more fun hands on stuff and later in life will become more basic skills like plumbing, rewiring a light switch, painting walls, planting trees, driving a stick shift, changing oil.
This post gets me so excited to have a boy to teach these skills to! (My dad has 3 girls so I know how to do a lot of this)
