for borders i always use 2 pieces of paper. the background piece (the one you want your border to be) cut to the standard size 2.5 x 3.5. then the front piece with your stamp image will be cut smaller depending on how big you want the border 2 x 3 or whatever. this makes a border without having to actually cut one out with exacto knife. hope this helps!

heres a pic of some of mine i did this with http://www.atlasquest.com/images/gallery/12/91/129131lg.jpg

Those are cool LTCs. I have done them that way before. I was kinda going for an oval picture frame sorta look so I may just cut my stamped image out as an oval. I was just curious if anyone had any method of cutting out openings that I hadn't thought of yet.
