I tried my universal darning foot I bought for my Singer on my Janome today. At first it wasn't working but then I had a "duh" moment, I forgot to lower the foot. lol The feed dogs were down but not the foot. Once I did that, it worked fine. I though I would have to buy one made for just for a Janome. Now I can practice FMQ...I think.
I hope you get your darning and the 1/4" foot working.
