Welcome to the Quilting Board!

OR

1. ## Darn math!!

Can someone please help me? I have an 8 inch center piece of fabric. I want to make the unfinished block to be 12 1/2. I want to sew half square triangles to the 4 sides to make a square in a square. What size do I cut the squares for the half square triangles?

2. Sorry, can't be done. For a 12" finished block that is a square in a square, the finished HST's measure 6" on each side. (Cut each from a square that is 6 7/8", or from a 7" square and then cut down the HST.) But the center square needs to be almost 8.5" finished, or 9" unfinished.

3. Question, is the center block 8 inches finished or unfinished?? Secondly, you want the center block to be square and then the side blocks to form a diamond around it and then a square around that, right??

If that is the case, you will be working with 60 degree angles. Much better to make the block 16 inches because the math becomes very simple. It would be a sawtooth star with the side pieces inverted.

4. It can be done if the center square (which I assume is 7.5", finished) "floats" in the outer triangles, which would have to be cut somewhat bigger to make up for the smallish center square. Not the conventional square in square, but attractive (and still a 'square in a square'). If I have a moment tomorrow morning, I'll try to work out how big those triangles need to be.

5. I have a panel that has pictures that are 8 inches unfinished. I wanted something simple for some corners. Thought sq in sq might be simple. Any other ideas? They are a panel of things from Cape Canaveral. Thanks

6. If you have 2 co-ordinating colours, you could do churn dash. Or you could use one colour (even just black or white) and just make 2 inch sashing between each picture.

7. If you want a "true" square in a square block (like the first pic), the finished size needs to be 15". If you want to make it with HST (like the second pic) the HST and the corner squares are 3 3/4" finished.

8. If you want to stay at 12" finished, you could try one of these:

The center square is 7 1/2" finished (so you can use your 8" pieces). In the first one the corner squares are 2 1/4" and the 3 center pieces are 2 1/4" X 2 1/2" finished. In the second & third ones, the corner squares are 2 1/4" and the elongated flying geese are 7 1/2" X 2 1/4" finished.

Hope these help! Good luck and show us pics!!

9. Above ideas sound great for your purpose. If you want to continue with your original idea, but with the 'floating' center square as I described above, here's how: Given your 8" squares for the center, cut 7 5/8" squares (2 for each center), divide on the diagonal, and apply to your original squares. For me the easiest way to center the triangles on the squares was to iron all pieces in half and use the fold line. My test square ended up just 12.5 ". Hope this helps; in any case thanks for the challenge to my aging brain! --nanibi

10. Oh thank you very much. I am going to do a couple "test" blocks and see which one works best. DUH!!! I didn't even think of a churn dash. But, I still call myself a newbie. LOL

11. The post from Cherisews just proves once again that we have some very smart and experienced quilters on this board. Thanks for giving some great and easy to follow solutions for this "problem".

12. Shelbie, thanks for the compliment! I love designing and creating blocks, so I saw this as a challenge. Had lots of fun! I really liked the 3rd block in my second post and was curious to see how it would work in a quilt. It gives a lot of play and motion:

Sustraley, have fun playing with all the ideas you've been given. Let us know what you decide on!
