This answer uses the first six steps from my ruler answer to the previous question. (LliwTelracs' answer is a better way of finding the same point.)
The labels are optional; they serve only to uniquely identify the points and creases.
Label the ends of a short side NW and NE.
Label the corresponding ends of the other short side SW and SE.
Clockwise from the top right, the points are NE, SE, SW, and NW.
1. Crease between NW and SE. Unfold.
2. Pinch a mark halfway between NE and SE. This mark is point $1/2$.
3. Crease between SW and $1/2$. Unfold. Where this crease crosses NW-SE is point $1/3$.
4. Fold the raw edge SW-SE to lie on point $1/3$, such that raw corner SW lies along the NW-SW raw edge, and raw corner SE lies along the NE-SE raw edge. Pinch a mark at the NE-SE raw edge end of the fold. Unfold. This mark is point $1/6$.
5. Fold the raw edge SW-SE so that point SE lies on point $1/6$, and point SW lies along the NW-SW raw edge. Pinch a mark where the NW-SE crease crosses the new fold. Unfold. This mark is point $1/12$.
6. Crease from point SW through point $1/12$ to raw edge NE-SE. Unfold. The NE-SE end of this crease is point $1/11$.
With another 9 pinches, it is possible to turn the 11" side of the paper into a ruler with one pinch every inch.
