I recently was given a Berina Bernette model 234 serger w/ out the manual. I printed one off the internet, but am still having a very difficult time threading it (lower loop - don't know if its the first or second). I wish I could be more descriptive, but I've never used a serger before, and unfortunately don't know anyone that has/uses one to instruct me. I've gone to local sewing/craft stores and they've been most unhelpful, since the machine wasn't purchased at their stores they're unwilling to help. Also, the machine is missing one of the plastic spool holders, no one seems to have one or knows where I can get one..............again if anyone can assist me I would greatly appreciate it, as I would really love to get to know the machine and get back into sewing again.
