I'm going to be attempting to make cloth diapers and covers for my granddaughter which involves using PUL fabric, and on the tutorial it said to use a walker foot. I have a Toyota EZ1 machine and it didn't come with one. I don't mind buying one, but I don't know if I need to get a 5mm one or a 7mm. On ebay there are both which say they fit Toyota (among others). There's not much on the internet about my model, even though I only bought it 7 years ago. I can ring Lincraft which sells the walker foot and see if they know what size my model takes. Anyway, failing that, can I sew the PUL ok without the walker foot? Thanks
