It would be difficult to make that block in an 11" size because, if you look at it, you will see that it is a 9-patch. In other words, you can divide that up like a tic-tac-toe board so that there are 9 squares. Four of the small squares are half-square triangles (HSTs). Each square is the same size, so you end up with a block size that is divisible by 3. The closest to 11" finished would be a 12" finished block. To make the 12" finished block, each square would be 3" finished. The block itself before being bound or sewn to another block would be 12-1/2" unfinished (finishing would take 1/4" seam off each side).
Edit: Here is a photo of a Bear Paw block that makes it clear why the claw portion is a 9-patch:

Here's a link to a free pattern for the Bear Paw block in 3 sizes. However, since you want just the claw portion to be 11", even the biggest of these sizes will be too small. Your best bet is to draw the size you want on graph paper. Once you have that, you need to add 1/4" seam allowance around each shape's outside edge to get the correct size to cut your pieces.
