I am trying to make a paper pattern for the Six Moon Designs Meteor that comes with a PDF http://www.sixmoondesigns.com/ultralight/myo_Meteor.asp. No problems there except that one of the pages shows a curved section.

A print out of the curved section produces an A4 page that is smaller than the curve needs to be in real life. There are two solutions:

1. Find a copier that enlarges and keep blowing up the page until it works. What a pain that would be.

2. Manually work out where all the points on the curve should be by scaling it up and drawing it on the paper. Tedious but it will work.

2 sounds like the go but I am interested in what other people do to solve this problem.

Im at the stage where I got to cut the mesh piece and I keep putting it off. I plan on just manually drawing the curves on heavy stock paper and using that to cut out the curves.
It would be awsome if SMD offered a life sized pattern.

Hi Petras

Some printers have additional options to tile an image over multiple pages.

There is a site http://www.blockposters.com that will chop up the image for you to print on individual sheets. Can't comment on it's use though.

Another option is to use some image editing software and just cut up the image yourself for printing separate chunks.

I'm unlikely to make it back to this post again. Sorry.

Just approximate.

Section the curve onto a very coarse grid on your paper and then mark out the same sort of grid on your fabric using chalk or a marker.

Just copy approximately the curve. It doesn't have to be exact does it? You're not going to lose marks for a curve that is off by a few degrees.

A 4×4 grid will probably do the trick…

I have used the 4X4 grid to both upsize and downsize patterns. With a little care it will come out with no problems.

Full size patterns can often be printed in one piece. Black and white plots are not expensive.
