I've never made this quilt, but I checked out the pattern on Fon's and Porter pages, and teh instructions for using the rapid -fire tool. It is strange that your blocks came out 2" out of size. Can you figure out which step went wrong? It seems to me that you may have used the wrong lines on the tool when cutting your stars.
If you trim to 1/4" outside the star points, how big are your blocks?
Can you post a photo of your stars?
I see a couple of options, but both involve unstitching the stars at least to some degree. The fortunate thing is that your stars are too big, rather than too small, so recutting is possible.
I'm going to reference the steps on this page
http://www.fonsandporter.com/content...oyne_Stars.pdf in the following suggestions.
1.
Less unsewing, but may result in stars that are a little differently shaped (long narrow diamond segments, rather than the true diamonds). If you want to try this, do it on only one star first, to make sure you are happy with the result.
- unsew the star into 4 quadrants (see picture J in the link above)
- Trim the *inside* corner off the square, to make each an even 5" square unfinished. Then, when you sew them back together with a 1/4" seam, you will have a 9 1/2" unfinished block, 9" finished.
For the smaller stars, trim the same way, but to a 3 1/2" square. That will give you 6 1/2" unfinished, 6" finished.
2.
I would say the "proper" way to fix it. Will give you exactly what you wanted, but requires more unsewing and you have to be sure you know exactly where you went wrong in the first place.
- unsew as above, but then unsew the diagonal seam on each quadrant, so that you have pieces as seen in picture I. Double/triple check which line on the ruler you are supposed to use, and very carefully align the right line with your coloured diamonds, as shown in the photo.
Trim the 2 outside edges along the sides of the rule. Re-sew with a careful 1/4" seam, double check the size of your new quadrants (should be as noted above - 5" and 3 1/2") and then resew the rest of the seams.
