Pinking rotary cutter?
 

I saw a pinking rotary cutter and purchased it because I had just started a quilt project with some cheap fabric that was making each block look like spaghetti squash innards on the back.

I sew the pieces, press to set, then trim the seam before pressing to the dark. It works very well.

I just wonder if I can use it for cutting the pieces, but it seems it would add an eighth of an inch unless I decided the up or down of the curve is true. Anyone use pinking for the first cuts?[ATTACH=CONFIG]541911[/ATTACH]

I've used the pinking rotary blade but not for cutting quilting pieces - as they need to be accurate.

Be very careful if you use it with a ruler. The shape of the blade makes it easy to jump over the top of the ruler and can be dangerous. Good place to use a Klutz Glove if you have one. The only time I use mine, and not for fabric, is in a cutter/ruler combo, not a rotary handle.

I mostly use mine to cut backgrounds for hand appliqué. It will be handled a lot and the pinked edges won't ravel.

it has been mentioned on the QB many times about precuts having pinked edges... do you use the innie or the outie to measure your 1/4" seam. in the case of cutting your own pieces with the rotary cutter, it would be the innie to measure your seam from since that is the edge of the blade against the ruler. not only be careful of the other cautions mentioned, but note that the cutter can damage the edge of your ruler. although it would be twice the work, i'd opt to cut with a straight blade and use the pinking blade later. you also might consider making your cut pieces bigger and sew a bigger seam allowance so that the pinking does not leave you with a very narrow seam allowance.

I don't use the pinking blade for making the 1st cut but I do use it when I go to cut apparel fabrics. Later though when I'm trimming my quilt after quilting it I might use the pinking blade so I don't get so many loose threads while I'm hand stitching the binding onto the back.

I had thought of buying one and then decided I wouldn't use it. I don't like sewing with the charms and jelly rolls that are pinked.

I used to sew garments and used pinking shears to keep fabric from raveling. If you can do that in garment sewing, I thought why not use a pinking blade for cutting my pieces to make quilts. Also I can not stand the raveling strings on the back of the quilt top when you use a regular blade. Using a pinking blade has worked out well for me. If you cut everything with a pinking blade, it should match up. You will have to change blades more often so that your blade will be sharp to cut through multiple layers. I watch ebay for good prices. I do not buy the off brand ones, only Olfa that fits my rotary cutter. I have not had a problem with the cutter jumping over the ruler, but I am always careful to make sure my fingers are placed well away from the cutting area when I hold the ruler down.

I've only used it for silk because I used a larger seam allowance. Otherwise I've used it to cut paper for decorations. I've seen Nancy Zieman use it to cut around curvy pieces, but not for precise patchwork cutting.

Thank you all! I had not thought of the ruler jumping possibility! Nor had I realized that charms come pinked. I think I will give it a try on small project.
