Help with size of square

If I want to make a 6 1/2 square what size do I need to make my
triangles. I want to do a pinwheel type block. So 8 triangles will make
up a square. I hope this is clearer then mud.
Thanx
Joanna

ack, i was going to type out what i thot but as i've already messed up one
post today, i'll shut up while i still can.
someone else can tackle this one.
sorry.

I assume from your description that your pinwheel block will be 6-1/2
inches finished size or 7 inches, including the outer seam allowance.
That means that each quarter, made up of two triangles, will finish to
3-1/4" square. Cut the squares for the triangles 1 inch larger than
that, or 4-1/4 inches. After you have sewn two triangles together, trim
the resulting square to 3-3/4 inches. Sew 4 of these together. It should
measure 7 inches (6-1/2 inches in the finished quilt).

Mud? You want to talk about mud? HoooBoy, do we have mud.
Meanwhile, back to the question.
Joanna, please do it the easy way. Cut a 3½" square of something and a
3½' square of something else. Put them down right sides together. Stitch
diagonally (can't use that word without thinking of Harry Potter) across
from corner to corner.
Flip open and press.
You can gently draw a line with a pencil if you're timid about stitching
accurately. If you're doing a mass production, you can put a strip of tape
(or a BandAid if that's what you have) on the -0- line of your SW and track
with that.
Okay. Now. Is that as clear as mud? What I'm saying is you don't have
to / need to cut triangles - you can just make them happen and there's no
fiddling with bias trauma. Polly

That's fairly wasteful of fabric, if you're going to be making a lot of
HSTs it's better to cut the square such that you can stitch a quarter
inch either side of the middle and get two triangle squares from two
starting squares, rather than just one. If you are accurate, you need
the squares to be 7/8 inch bigger than the finished size, if you prefer
to trim to size, then go for an inch bigger.

Cheers

yup, those are HSTs aka half square triangles.

i'd start with 3-7/8" inch squares, if you sew perfect seams,
if not, cut them 4 inch and trim after you get those HSTs,
to 3.5 inch then join the 4 of them into your pinwheel.
that pinwheel should then measure up at 6.5inches and
when joined to other blocks or fabric into the quilt top should measure up
at 6 inch.

after you stitch'em 1/4" each side of that drawn diagonal,
you cut along the diagonal line between the two stitching lines.
four different fabric squares will give you 4 HSTs (2 sqs make 2 hsts).
sew those 4 hsts together into your pinwheel.

mud mud glorious mud.

hoping i didnt mess that up, argh, nothing goes right anymore

Anne, I beg to disagree and hope not to be disagreeable. The method I tried
to give Joanna is fast and simple. I concede that it wastes some fabric but
it does not waste time. For some of us, time is precious. Polly

You're actually making 4 half-square triangle squares, each one of
those 3.5". Cut 4" squares, 2 of each color, layer RST. Draw a
diagonal on the backs of the lighter squares. Sew a very scant quarter
inch on each side of the line, then cut on the line and press open.
Then trim your squares to exactly 3.5", using a little square ruler so
you can line up the diagonal seam.
