That surely is the "Double Aster" block and the pattern and directions can be found at www.quilterscache.com Just look for their pull down menu which says something like "where do you want to go today?" Go to the "Free Patterns". Then you can either look up the pattern in alphabetical order or by size. This pattern makes a 12" block, which is 12.5" unfinished.
If you are not familiar with Quilter's Cache, it is one of my favorite sites. It is good for reference, free pattern blocks, layouts and free templates.
You can print out their patterns on your home printer. Just a FYI. If you print a pattern, be sure to look down at the bottom of the page you print and see it there is a page 2 and a page 3. You must print each page seperately. It does not automatically go to page 2. If you don't do this, you will end up with only the first page of your directions. Also look in the top right hand side of the page and see if there is a link to templates, if they are needed for that pattern.
Hope this helps.
