My Eversewn Sparrow 30 was delivered on Thursday. Really nice machine. I have two previous walking feet and both fit on the Sparrow as does the other sole plates. In the manual it specifically said though only use a walking foot when nothing else will work for you. For that reason, will use my other machine when its time to do bindings. The Sparrow's harp is only 6 1/2", like most other standard machines.
