Taking in dark gray jeans
Before
My husband's jeans were too roomy in the waist.

Before: we pinned the jeans so that they fit.
After
I measured how much we had taken in with the safety pins and took them out. Using those measurements as my guide, I sewed two darts in the back of the jeans.

After: You can see the darts on either side of the belt loop.

After: the jeans stay up without safety pins!
