that's a tricky one. if it's only a little off, i square it so that i have the 1/4" seam allowance needed, even if that causes a slight bulge in the center. if it's more than a little off, i'll resew it more accurately.

If the block is slightly larger than the required size - use your points and measure 1/4" from the point to the outside edge to square it.
If the block is slightly smaller than the required size - I generally leave it as it is and try to compensate by using a smaller seam allowance. In other words ... when I match my star block to the next block/sashing/border I will match it to the POINTS of the block, not the outside edge of the block.
If the block is smaller than 1/8" on ANY side ... I'll deconstruct it and re-sew.
Make sense??

Sharon Schamber has some videos on Youtube that show how to square up a block using starch and pins. There's only so much you can do with an 8-point star to square up because you absolutely must leave enough seam allowance so the points are not chopped off.
If the block is too big, even after blocking, you may have to ease the block edges.
If the block is too small, you may be able to "float" the block in order to preserve the star points. A basic way to make this work is to have sashing the same as the background color of the blocks. Here is an example: http://www.bamrobot.com/pz-inch-7-su...35Ktzkjpg.html

It's really hard to make an eight point star block bigger! I'd agree with Sue, match the points, not the seam allowances..but you must have at least 1/8th inch! The absolute best thing to do when you're making a difficult quilt is to buy extra fabric to begin with, because it will all be gone everywhere if you look for it later, trust me!

I do as others have suggested by squaring up ensuring the point has a 1/4 seam above it. At this stage you can adjust if needed. Once you have cut the fabric no way back so leave ears until doing major cut.

....if you don't get that 1/4"seam allowance automatically as you are piecing it then means your 1/4" seam is either too thick to too skimpy....I personally would NOT trim to 1/8" if that's all you have...that's a sure way to get a raveled seam after washing...not enough fabric their to hold that seam together.....
