how do you downsize a quilt block pattern (ie a 12" finished to a 10" finished) is there a formula to use?

[doodlebug]

yup...if you use a photo copier-

to enlarge:

(size in inches you want the block divided by the size of the orginal in inches) multipled by 100 = % to enlarge on a copier

to reduce:

(size of block in inches divided by the size you want the block in inches) mulitpledby 100= % to reduce

for your 12" to 10" you will reduce the block by 83.3% on a copier

did i help?

Although I have yet to use it (I dislike math), the "Quick and Easy Block Tool" has directions for changing block sizes on page 107. If you don't find what you need from the above responses, drop me a line, and I can copy this for you.
