Blocks on point - what size inset triangles?

here

I am not very smart about such things lol... But those triangles on the edge are the same size as the other blocks in the quilt. So would you not just make the squares the same size (14 in finished) and then cut them on the diagonal. (ie the alternating block in the quilt cut in half) Those ones on the corner however... you need a much smarter person than I... I cant even figure out the website someone posted.... And to think I can complete complex physics and algerbra equations, but basic geometry is the enemy of me lol. Anyhow I mostly wrote because I really like that quilt and to say thank you for posting it... I may become a copy cat ;)

No you can't do it that way. You lose the seam allowance and come up short. It's a bit counterintuitive....until you try it.

Howdy!

Amazing how much that looks like the Bear Paw block, huh?

Here's another calculations page for diagonal blocks:

That's a nice site Sandy. Very clear and to the point. I'm bookmarking it.

Thanks Sandy.....perfect!!! I've printed it off to keep with my pattern.

However, I will have remember to break down my squares in smaller sections as the finished block is 14" and I have to keep the inner triangle pattern for the alternating blocks. But when I get that far along in the quilt and visual I'm sure I'll figure it out.

Thanks Jennel........I've bookmarked it. I've done on-point quilts before but it's been a while. They have a nice tutorial there for a fresher course.

That occurred to me thank goodness, that's why I came here asking the questions before I started any cutting.

Careful Carissa - if you do that, you get the bias edge on the outside. This is to be avoided wherever possible!

hmmmm see why me and geometry didnt get along. bias edges on the outside would be no good... I just had an issue with that... not because of something I did mind you, but it did make for something that is twisted in one spot if that makes any sense. The bias edge was in the middle of a piece up against a lot of non bias edges and it twisted the finshed piece. Good thing it wasnt on anything important lol. And again, that is why I stick to patterns with explict and specific instructions... if it is left up to me in any way, guarenteed it will be messed up lol.

Carissa PS when you create this quilt, can you pass on the specific instructions so I can be a copy cat ;)

If you can't figure it out - the calculation is one of the more complex ones (square root of double the square of the block size, plus 1 1/4, if you must know!), one way is to draw the finished block size and measure the diagonal, this is the finished size of the quarter square triangle needed for setting, then follow the usual quarter square triangle rule of adding 1 and a quarter. You can always add a bit more as lots of people prepare to cut it down once pieced, or leave the blocks to float.

I just finished a miniature quilt top like this. The first time, like Carissa, I though the side blocks would just be the regular size cut in half. NOT! Then I just cut them huge and trimmed them down.

I wasted fabric, but they were only 2" blocks so it wasn't a whole lot. But it was my Keepsake black, for gosh sakes.

Nope, doesn't quite work that way. 1st, you probably want the long edge of the setting triangles to be on the straight grain -bias edges are a PITA. So you need a very big square cut diagonally both directions = 4 setting triangles. I don't bother with formulas. Fold a finished 14.5" block in half diagonally and lay it on the cutting board to find the measurement of the big square, plus an inch, and round it up to the next whole number. This will give you lots more than you need. But then you can trim the edge of the top later with plenty of allowance for error! The 4 corners, of course, are simply 2 squares cut in half diagonally so the long edge is on the bias, and

I understand why bias on the outside would give twisting problems.

What I can't understand is why the blocks don't cause problems when set on their bias. Debra in VA See my quilts at

You mean it takes geometry to make a quilt? OMG! I can't do geometry! Wait a minute, how did I make a quilt if I can't do geometry?

Algebra and physics are beyond my abilities too, so I wonder if I've used them somehow. Debra in VA See my quilts at
