U can use 2 thrends of floss for 11 c fabric. Have fun.

Two strands will not cover the fabric well! If you.must use 11 count, test the coverage with just a small block.of cross stitches in a margin..The framer won't care and it helps you to see the coverage. I would try three syrands and even four. I don't like the coverage of two stranfs on 14 count, so I know it won't cober 11 count fabric.
