I have learned to check the grain lines (the way the threads are laying) before buying a panel print.

If it is printed off-grain - it is printed off-grain. You can stretch it and pull it and stand on your head - it will still be printed off-grain.

I would attempt to trim it -on grain - if the design permits that - and go from there.

I have learned to check to see if the panel if printed on-grain before buying it.

If the design is printed off-grain - you can stretch the fabric, pull on it, block it - stand on your head - the design will still be printed off-grain.

You basically have two choices when attempting to work with a panel that is printed off-grain -

1) keep the grain lines perpendicular and do something with the design - trim it, sash it, whatever

2) get the design "right" - and live with off-grain fabric that will revert to it's "normal" unless stabilized some way.

Some spray starch and pressing may help straighten your panel. All of them crooked.

Most panels are not printed on the straight of grain.

I never prewash fabrics. I use spray sizing and a steam iron. I could not get the panel straight. I used a square in the
corners and straightened it best I could. First I trimmed off some of their borders that came on the panel. I then started to add my own [ATTACH=CONFIG]526382[/ATTACH]border strips. After each set of borders I would again use a square and trimmed. At the end the panel was still not perfect but much better than when I started.

I dampen the panels a lot, very wet, then I stretch and pull them and pin them down onto a canvas. The ones you can buy at any craft store for framing a picture. Let it dry this way and you should be good to go.
