Teach a man to sew....

....and he'll take in his own t-shirts for life. (I hope).
I recently taught my partner how to take in t-shirts and since then he's been hooked. Because of his height, t-shirts that fit him in length are usually way too wide for him. Now that he knows how to do it himself hes been on a roll and has been adjusting almost his entire wardrobe.

Here he is working away.
