This simple purse fully lined. I added a key ring to one end of the 'string' or whatever you call it; and a hook to the other end so it could be hooked-on to bag or whatever the user wants to hook on.
The 'string' is not sewed on to the purse itself, so it pulled out (with the keys pulled into the purse) to make the 'string' long enough to use as a wristlet.
Using Machine to do this is so difficult. I should stick to hand sewing.
