    I am so far very happy with my new serger. The threading was a little harder than I thought it would be .

    Juki MO50eN 3/4 thrread serger

    Posted by Arlene Hanna on 28th Oct 2017

    My Second review of this serger. Felt I needed to revise my previous review. I recently switched my thread to stretch threads for stretch fabrics I am sewing. I am finding it impossible to get the Juki to handle woolly nylon, woolly polyester or even C&C stretch thread. Thread constantly breaks, needles break or the thread bunches up under the plate and makes a mess. It''s back to my tried and true Janome basic serger 8002D which has always handled the stretch threads with no problem. The lower looper mechanical threading on the Juki is a great feature but with so many stretch fabrics today I want to be able to use the thread of my choice.

    If you are thinking about purchasing a basic serger this one should be a top contender. The automatic lower looper threader at this price is a bargain. Even though I have a Janome basic serger which is a good machine and is working just fine it does not have the automatic lower looper threader/ While tieing the old thread to the new and pulling through works most of the time there will be instances you will still have to thread it through yourself. I have had the Juki about a month, use it almost daily and so far am happy with the stitching and thrilled with the lower looper threader. My recommendation it now
