Good Morning,

I've always used a copier to resize any pattern. There are several office printing shops around and they will reprint for me. I haven't done this recently but years ago I paid up to $1 and was tickled to get it done.

You use to be able to purchase a machine to enlarge a picture with a projection on the wall. Did you look for anything like that? These were from years ago so may be obsolete.
Just a couple thoughts for you.

How big does it have to be? My printer/scanner like most does up to poster size which entails feeding several sheets into the printer, but it works. I also own a projector which does come in handy for really large images.

I was lucky enough to be give a copy machine and use it for most of my enlargements. For some projects I have to use the copy I enlarged and enlarge it even more, which often means I have to physically cut and tape several sections together to get a finished pattern.

For simple patterns where you need just the basic lines or where you can't get a clear copy to enlarge, I do the "squares." It takes time but always works. I place a sheet of tracing paper over the project and square it off. Then make a sheet of larger squares on newsprint and place tracing paper over it and draw away. I use a very fine pencil or marker to do the squares. I did a life size Santa that I had drawn on a 4"x6" note pad using this method. I enlarge it on a copy machine several times then did the squares. I made him for my daughters & family and ended up making and selling 16 of them.....never again!

Hope this helps!

PS...if you have a electronic fix it shop near you, check it our for a copy machine.

A BIG OOOOPPPPPSSSSS! After posting all that stuff up there-I stopped to think...something I rarely do....and figured out you are looking for a computer programs to enlarge your patterns! Daah!

The only site I know of is Pixresizer. But I use it to reduce pictures, however some of my Pez friends use it to enlarge pictures. Might be worth checking out.

Thanks for all your help. I did pretty good with my scanner and croping several times. I will try the Pixresizer.

I know this post is a little old but I use one of these and it was worth every dime
