Here's a quick tutorial to show how I make bear paw blocks...

Paw fabric: cut one 5" square and one 5 3/4" square
Background fabric: cut one 5" square and one 3 1/16" square

The reason these measurements are a little 'odd' is because I wanted to make half square triangles (HSTs) the easy way and it just was simplest to start with 5" squares for me. It does mean you can use charm squares but beware that you need a bigger square of fabric for the largest part of the paw. The block will end up (a very random) 8 1/4" but I'm doing a whole quilt of them so it doesn't matter much. It wouldn't be too hard to resize. 

Start by putting the 5" squares right sides together and sewing 1/4" around all the edges, then cut on the diagonal both ways so you end up with 4 HSTs. 

Open out and press the HSTs. Layout your block with the squares. Here's is a guide for how to assemble the block:

It is made of two parts (shown by the dotted white line) that you then sew together.

To make sure the seams match nicely press the two sections in different directions and butt the seams together:


Press the seams of the HST blocks towards the 'paw fabric' and press the joining seams open to reduce bulk.

So that's my method. Once you've done a couple you can chain piece the different sections.

It's a little addictive! Happy sewing!
