Bags, wallets, etc are quite fun, and you can find lots of options from the easy "two rectangles and a handle" to some clever backpacks and custom bags to hold specific items.
It is quite cool to have a bag with custom pockets designed specifically for the things you actually own and carry often, in the color and fabric _you_ like.
Clothes are harder as you need to learn how to fit them. But doable.
And pattern construction (aka "drafting") is a whole separate engineering discipline. Check freesewing.eu for inspiration.
