Confused between sergers with lay-in threading and knob type ? Here is your answer.
Whenever you look for a serger, you will be presented with two versions of threading, one is the lay-in threading and knob type is the other one. You can’t clearly say one is better than the other, unless you have experience using both. Modern serger manufacturers seem to prefer the lay-in tension type. Most of the recent models come with lay-in threading and they seem to promote this as a premium feature as well. People also seem to prefer lay-in threading sergers. For example, Brother 1034D is the most popular serger in US and it comes with lay-in threading.
