Pros : These are perfect for a smooth straight line, great for boarders, but I like using them kinda like tape to hold two colors together on a base next to each other without pulling away from each other. They also work for accents and details in designs.
They are so thin you can snap to a good length with your fingers, but if you want precision, you can use a cutter and pliers to get just exactly the right length and angles.
Cons : I wish I could get all one color, but then some of the colors in the mix don't seem to be available on their own from Oceanside. /shrug
Also, it can be hard to tell which ones will turn opaque or strike (change color) when fired.so it's often a good bet to break off just a bit from the very end and run it through a cycle to be sure.
Other Thoughts : Nip them into squares (can be stacked for large dots/color saturation) to make uniform dots quickly and easily.
Another trick is to put several on their sides next to each other and place on a base glass to make thin stripes
I also like taking the niped squares and using them like mosaics on clear base glass then firing face down on a tack fuse.
