So I want to trim some prefolds but have no idea what excactly I need to do this successfully! What kind of needle and what brand is best to use in the serger? Also, what kind and type of thread is best? (I would really like to do something pretty like veriegated (sp?) thread to dress up these boring 'ol prefolds. Feel free to spam me with links to places you like to get these things! What kind of thread do you like to use in the straight needles? I have a Simplicity Differential Feed SL4350D if anyone is familiar with this serger (I am just learning to use it!). Sorry for all the questions and I am thankful for any help you crafty creative mommas can give me! Thank you!
you should use whatever standard needle your machine takes and I always used maxi lock variegated serging thread in the "loopers" and regular high quality sewing thread (I used maxi lock as well but a different kind) You might want to take the brand of your serger to your local fabric store and they should be able to set you up with the thread and needles you need.
Just a tip it is a pita to change looper threads so you might want to go with a nice bright variegated thread instead of trying to do a rainbow of colors
Depending on your prefolds, you may have trouble sinking the needle through that many layers. I have a LOT of trouble with my thirsties. No wonder they hold so much. I found the trick for me is to only use one needle for a 3 thread stitch. I also use the heaviest duty needles I can (think I have some denim in right now).
