OK, I must admit to everyone that, even though I've been sewing for 40 years, I am mathematically and geometrically challenged. Does anyone know of any simple method (that I can understand) to enlarge quilt blocks. I'm a dork and still trying to teach myself simple equations, even though I've had a home sewing business for several years. I'm OK with doing calculations but I'm not sure what calculations to do to enlarge a block. Thanks in advance for any and all help anyone can give me.

Take what you want and divide by what you have. Works for enlarging and decreasing.
You can use this measurement for individual pieces when rotary cutting.
I have a wonderful chart that tell you exactly what to do, If you private message me you email I can send it to you as a pdf file for you to keep.

You had me doing math to see if that worked....LOL. And sure enough it worked to enlarge as well as decrease. I guess I had never really thought about how I do it. I always looked at the number of squares in my block and decided how big they had to be to make my block the size I wanted...LOL

Okay the BSC strikes again. I can figure out how to enlarge a block but I'm totally spaced on what Kris means by taking what I have and dividing by what I want..
Life is like a quilt...bits & pieces, joy & sorrow, stitched with love
I know this is going to be really stupid, but, once you get the percentage of enlarging the block, how does that translate to enlarging the pieces? I'm so sorry I'm so dense.

Elizabeth, would you mind sharing your chart with me?

Spudgramma, you are so funny, at least I hope that was a joke...

It was sort of but I really am confused about what she meant LOL

You multiply all the cutting measurements by the number you got when you divide.

You divide what you want by what you have.
If you want a 9 inch block and have a 6 inch block you would divide 9 by 6
9/6 = 1.5
you multiply 1.5 by 100 you would enlarge by 150%
if rotary cutting multiply you measurements by 1.5 to get the new cutting measurements.
Kris: If you have a 6 inch block and want a 9 inch block you would divide 9 by 6 9/6 = 1.5 you multiply 1.5 by 100 you would enlarge by 150% if rotary cutting multiply you measurements by 1.5 to get the new cutting measurements.
If you have a 6 inch block and want a 9 inch block you would divide 9 by 6
So you would multiply each piece of the block by 1.5 (in your example) to get the new cutting size??? See I told you I was confused. :(
That's correct Spud

If for example you have a 6 in block pattern and you want a 4 in block you divide 4 by 6 which gives you 0.66 or 2/3. Then you would divide each square size by 2/3. 3 in squares divided by 2/3 equals 2 in squares which would make a 4 in block.
Holy moly I hope I NEVER have to increase or decrease a block!!! LOL
