Alondra,
I think you may be thinking of the one that is on Murphy Road, just north of Hwy 6. If you go north on Murphy from 6 it will be in a shopping center on your left not too far up the road. they have Babylock machines and I discovered it while looking for serger classes. I can't think of the name of the shop right now either but I will let you know if I remember. Does that sound like the one you are looking for?
