I've found a few tricks with seams, though they don't always work because of where they are. One is the tape method, tape along the outside seam the two pieces together, then glue from the back and press together, peel off tape after it cools. Another is just judging how much glue you're putting between the pieces, when you put glue on one piece, spread it out a little so it doesn't all push out when you press two pieces together. Another method is to cut your pieces so they are only flush on the outside, but a little apart on the inside, so it makes a valley, then full with glue from inside. And probly the most common method for me, if globs push out when you press the pieces together, lick your finger and swipe it across the glob quickly so you don't get burned, it will cool quickly then you can peel off the excess. Another piece of advice, change blades often! Since I started this suit I've been through over 100 blades! Keep them sharp!
