Welcome to the Quilting Board!

1. ## Is there an easy answer to this?

I am very new to quilting and am trying to design my own quilt. I have found several blocks that I like but they are of different sizes. How to I know what size to cut if the directions are for a 12, 9, etc. block and I want a block that is much smaller? I bought a calculator to help me but it doesn't address this situation. Can anyone help me to understand the math involved?

2. You could graph it out and divide your graph by the finished size you want. Don't forget to add 1/2 inch to each piece for your seam allowances.

3. Check out Quilt.com as a reference for all kinds of blocks, all different sizes. If you are designing the block yourself, graph paper is a good way to go. Also think in terms of the number of units in the block. For instance, a 4 patch that finishes to 4 inches square needs 4 squares at 2.5 inches each. A 9 patch isn't going to be able to be easily divisible by even numbers, as there are 3 squares across. I think in terms of there being "even" blocks and "odd" blocks in terms of size, so there are 4, 6, 8, 10 12, etc and there are 3, 9, etc. A 12 in block is a nice size to work from because you can make it in either "even" numbered units or in "odd".

Delaware quilts has a good math hints page.

5. Try this: www.victorianaquiltdesigns.com
scroll down to red lettered things under "free..."
click quilt calculator charts
scroll to Quilty Formulas and click on "request this free..."

They have several things there that are very valuable, I think. Good luck.

6. best way is to gradt the blocks out in the sizes you want then add seam aowance and make templates or use measurements for rotary cutting. Although is is difficult to give an informed answer without knowing what blocks you want to enarge or reduce.

7. I was going to suggest, if you post what particular block you are wanting to change the size on, many members might have a link to the size block you want or might offer to draft it in EQ for you.

8. graph paper--dont forget your 1/4 inch seams--also you can build up your smaller blocks with added stripos

9. Check out my recent post near the bottom of this page .... http://www.quiltingboard.com/main-f1...ml#post5701181 ..... for using graph paper to solve problems like this.

10. I would resize them for you in EQ

What a great link! I particularly liked the info on setting a square on point. Thanks!

I swear, someone needs to run a few "math" quilting classes. Converting most angular blocks to a certain size is soooooooooooo simple, but it just baffles some people. A half an hour class would solve those problems.

13. I think this is the kind of math that a teacher once told all of us that we would use someday, but we just don't know when.

And changing block sizes is just second nature to me.

15. There are some great books with different sizes for the same blocks - Around the Block by Judy Hopkins comes to mind. Also, the "All in One Block Tool" is my Bible. There are also some apps for iPhone and iPad.

16. This is a great site. I had not heard of it before. As for questions on this board; I am 65 and have sewn most of my life but have learned so much from this board that it still facinates me.

18. EQ is definately the answer. If you want to design your own quilts ask for it for your "toy gift" for xmas. I've owned several versions of EQ and it keeps getting better and better. Dianne said she would resize them for you, but if something happens and she gets too busy, I would also be happy to resize them for you. Happy stitching.

19. Use your printer/copier and the chart provided in the site below to make it as easy as pushing a button:

20. This might not be what you want, but could help. If you know the largest block that you want to make, you could go ahead and make that block. Then you could add simple fabric strips to the smaller blocks to make the smaller blocks the same size as the larger one using the strips around them. You could use a contrast fabric to make the smaller blocks stand out or you could use a background fabric that matches the larger blocks and the smaller blocks will just show up in different places around the quilt. I don't know if this makes sense, but in the end, all the blocks will be the same size for putting them together.
