you sewed three 2.5 x 6 inch strips together and that made a 6 x 6 unit?
if that's what you did, you "lost" a half inch in the seam allowances - so at this point, your four-unit square should measure 11.5 inches
after those units are sewn together, they will "finish" at 11 inches
if all your units are ending up the same size, it should go together just fine
do you use commas or periods/dots when you separate the whole number from the decimal part of a number?
I get so confused when people say "finished" or "unfinished" size - to me, "finished" is the amount that would show after the blocks are sewn together - "unfinished" is the size of the block before it's put into the top
12.5 unfinished will be 12.0 inches "finished" size

I think that if you sewed three 2.5in strips together with quarter inch seams, your little block shoud have measured 6.5in. You must be taking larger seams. When you look at that little block, from the front, finished, the first strip should measure 2.25in, the middle strip 2in, and the other edge strip 2.25in. , total 6.5in.
If you have four 6.5in blocks sewn together, then the completed block should then measure 12.5in square.
If you have four 6.5in blocks sewn together, then the completed block should then measure 12.5in square.

How long did you cut your sewn together strips?

When I did this first at a class, the instructor had us measure several different spots on the strip set and take the narrowest measurement. For instance if your strip set measured 6" in two places and 6 1/2" in another spot and maybe 5 3/4" in the narrowest spot, then we were to cut then strip set into 5 3/4" squares. What I always found was that my 6" strip sets were never that far off, just generally a scant amt...but I was always careful to use the lesser measurement to cut my squares. I imagine this is about as clear as mud, isn't it? Sorry, but it does make sense once you have done it.
