I saw those metal tips for sale somewhere not too long ago. They come in a set of 7. Google something about metal tips for glue bottles and maybe you'll be able to find it.

Very cool! Love the look! Now to learn how to do this.

I found a lot of places that might have the metal tips, but haven't ordered any nor shopped for them.
http://www.clotilde.com/list.html?cat_id=18 has something.
SoftExpressions.com is another one
Mayco sells an 18 gauge applicator which is too big. I didn't find any other sizes there.
Annie's Crafts has Glue Caps and Needle Tips.
Michael's might have the metal tips by the stained glass/glass painting section.
Some JoAnn's stores have the tips with paint bottles and brushes. Apple Barrel acrylic paint has a tip.
Hobby Lobby might have them in the craft department.

The knife edge binding looks good for the quilts that are hung and don't get washed too often. For the mitre corner bit couldn't one just after sewing the straight sides down on the back, the across ones could be folded at the corners at the 45 degree angle which would make a mitred frame on the back. A different idea for the gluing and ironing of the regular binding is one which I haven't tried but Judy who runs an online business in Australia told us she sews her binding on with fusible thread on one side and then irons it and the binding stays stuck on for easy handstitching without pins or clips. (Or machine sewing I guess.) I would imagine you would place it in the bobbin and then sew so that when the binding is folded over it meets the fusible thread there rather than where it left from if you get my drift.

I always learn something new at on this board! Thanks so much!

I saw another great tip on this board recently. They suggested not pressing the binding in half before sewing it on the front (or back if you that first); just hand fold it and sew it on. Not only does this save you the trouble of pressing it in half, it also folds over more smoothly to the other side when you're ready to do that part, since it allows the fold line to readjust itself ever so slightly to make up for the fact that the inner half will be slightly smaller than the outer half. I've tried it already on 2 quilts and plan to do it that way from now on.

I've enjoyed this discussion and the interesting tips and techniques. Thanks.

For those who garment sew, just think of the knife edge binding, as shown in the first picture, as a narrow facing. It could easily have mitered corners; just fold extra fabric in instead of just folding over at the corners.

I use to hand sew bindings to front. I heard they should be hand sewed to the back. There is never just one way to do something. There are no quilt police on here either. I'm with Jan, I also don't care for the knife edge.

I can't grasp what this knife edge is. I don't understand how you do it. I read everything and looked at all the photos and am perplexed. I think I need to see a video of it to totally understand what you all are talking about. I don't like binding and if this is something I might like, I would really like to understand it. Any videos out there? Help!!!
