I'm trying to make corner triangles and the ones in between the tulip blocks. I'm having a hard time figuring out what size to cut them.

Can someone please help? I did this in EQ5.

block size is 12" (tulip)
inside rectangle is 38 X 50
1st border 4"
2nd border 6"

The quilt is supposed to be 58 x 70 finished

I sure would appreciate it. I'm trying to learn triangles like these, but just don't get it yet :cry:

Thanks!

Ok, that just made my head hurt!

Wouldn't the inside triangles be....ok. lets see if I can explain MY thinking on this.
Take a square, the same size at the tulips, then make a triangle out of it. That SHOULD be the size of what you need.
But, that's my thinking.
OR, this is what I'd do too....not sure anyone would agree with me...
I'd take a BIGGER triangle...sew it to the corner, then square it off. Then measure it, including the 1/4 in seam allowance that that would be the size you would need.
I'm probably way off on this, but in my head, it would work for me.
Does it make any sense???

For half square triangles, take the finished size and add 7/8 of an inch and cut a square that size, then cut in half diagonally from corner to corner. This would be for your corner triangles as the bias edges will be attched to the quilt and the outside edges will end up on the straight of grain.

For the smaller ones, you will want to cut those as 1/4 square trianges so the straight of grain is on the outside long edge. Sorry, I cant give you the math on that one.

You could cut a template and add the 1/4 inch seams, then measure it and see what it measures.

Ill see if I can find the math for those.

Someone else will probably be able to give you the answer before I can find it though

OK, I found it...
Quarter square triangles are cut using the finished size plus 1 1/4 inches.
Then cut in half on the diagonals both ways.... leaving the straight of grain on the long edge...

So,

For your big ones this is what I think...

Since your blocks are 12 inches and the triange spans two of them,
you would cut your square 24 7/8 inches and cut in half on the diagonal giving the big corner triangles.

The little ones are also based on this measurement, I think,, so
cut the square 25 1/4 and cut in half both ways giving you four triangles from each square with the straight of grain on the long edge.

I would do it with freezer paper first to make sure it fits..

Oh yeah, you need to measure your quilt blocks to make sure they ended up 12 inches as planned...

wow i cant help you with the math but that sure is going to be pretty when you are done remember to show it once you are done
is that from a book or did you design it ???

Let's see... The big corner triangles:

if you look at the upper left you have two blocks side by side they are 12.5 unfinished, and when you sew those two together they will be 24.5' Cut a Square with sides of 24.5" Now cut it twice diagonally each way. Now you have the four big corner triangles you needed. SIMPLE. :D Now here's a big tip. if your blocks are a little small and your triangle is a little bit big find the center of both, pin from the center out, this will put any extra in your seams.

The little Triangles on the sides:

These are easy. Your blocks are 12.5 unfinished. Therefore the two sides are 12.5. Take one 12.5' SQUARE cut it in half diagonally one time and you will have two of those little triangles. Since you need 6 of these little triangles cut 3 squares.

See no math. :D

I love this pattern it's beautiful!

Thank you ladies.

I bookmarked that site Loretta.

I have a dumb question..which one is the long edge? Is it the one that butts up to my tulip squares? (told you is was a dumb ?) :oops:

You could also figure out the size for the small triangles, then instead of making big triangles, make the big ones as two small ones with a centre seam, and they will be the exact same size as the other small ones. Sorry i cant figure the size, i would have just sewn them oversize and then trimmed :) But very very pretty quilt, just love it! :)

The long edge on the big ones is next to the blocks, the long edge on the little ones is the outside, not next to the blocks.

The other two sides will be equal..

if you can find Fons and Porters book on Quilting it will tell you how to do it It is a vert good reference book one I have used for 30+ yrs Good Luck I will try and look it up for you
