It's a rotary bobbin with vertical setting and the feed dogs aren't an issue as they are easily removed or covered. I haven't measured it precisely but it looks like the bobbins are 1/4" by 3/4" and the Singer L bobbins may or may not be too big. The Singer 15 & 66 are too big. The New Home has a very different foot attachment method. I have a nice standard foot that's 1/4" and several attachments but not a darning foot. No modern company makes them so unless some one scores one in a box attachments or has another resource, it may be a new hunt for a darning foot. I can FMQ without the hopping foot but with a darning foot. So I'm looking for a darning foot. Not much hope if MacyBaby with her immense attachment collection doesn't have one yet ya just never know. At least a darning foot would be smaller, cheaper & easier to ship than a machine.
