some one mentioned that putting paper in between layers of Ripstop allows you to cut multiable layers of Ripstop at one time with out them sticking together....

Could some one please elaborate for me....last time I tried to cut more then one layer it was horrable!!!

I've tried it myself, with nasty results every time. It's a great way to edge-bond multiple layers together, though! Embarassed

Dick Barns of Pizzaz kites does it. He just uses a very sharp Hot Knife and cuts on glass.

Then when he wants to seperate the layers he pulls apart a small section and that allows you to insert a thin ruler. Just tap the seam around the edge, something like opening an envelope with a letter opener. (I bet a letter opener would do the trick here, too.)

At least this is the way I understood it when he told me how to get the pieces apart on a kit he sold me. It worked at that time.

Watch which way the grian of the fabric runs when you pull the layers appart....

test on some scraps...

If someone is willing...

Do some tests and post your results.

Take a couple pieces - don't tack them together - and make a few cuts. Then pull the pieces apart from BOTH ends and see which way produces the best results - i.e. no 'pulls' along the hot-cut edge.

Here's a guide to 4 basic 'cuts':
A: Along the scrim
B: Diagonal to the scrim
C: Askew to the scrim
D: multi-directional

We've probably ALL done this, but haven't really committed it to memory. Only after I've messed up a piece do I take note. Embarassed

could someone define scrim?

I have finally gotten a grasp on bias now you go throwing around a new word of the day for me....

The scrim is the quarter inch grid of heavier thread that makes it (ideally) stop rips.

Okay, I've just tried to do this. I put one sheet of PC-31 on top of another.

The best results seemed to be with a Hot Knife that was moved quickly around the template. If I draged it slowly it seemed like the pieces were welded together better.

It didn't seem to matter which direction the cut was in relationship to the grain of the fabric.

Not at all scientific. I made no attempt to quantify anything.

So, in the future if I'm going to cut multiple pieces at the same time I'm going to cold cut.
