Nope, not practical and not for me. It is too large and what do you do with the pins once you remove them while stitching? I have pin cushions at my cutting table, at my sewing machine, at my ironing station and usually somewhere else in the room. Certainly not going to have four of these sitting around. Also, I use the flat head pins and it didn't appear that this machine would accomodate those. Oh, well, doesn't matter because this is a gadget I wouldn't purchase and I have tons of gadgets that I've purchased and still not used. Not even tempted by this one.
Don't believe that June Tailor Co. has a hit with this. For those who might possibly be interested (can't imagine why), they should hold off because they will be on deep discount soon.
