Seam rippers are designed to be used to actually split the thread between the seams, hard to explain. You can cut the first few stiches (about an inch) and then separate the two fabric pieces, you kind of pull the fabrics away from each other and run the ripper down the stiched seam, it is VERY fast, but you have to be extremely careful as you can actually rip the fabric (which I have done mayny times) so the safest but most tedious method is the Sherrib tecnhnique described above, I use tweezers to pull out the threads but I am going to try the lint roller technique, or if you can get your hands on a hemostat (a surgery implement) those are fantasic for pulling out all these little threads.
