Trying to make a royal icing recipe which calls for Meringue powder, but cannot find it anywhere. Would powdered egg whites be a suitable substitute?

I'm pretty sure I've used both in the past with equal success.
Ive used powdered egg whites for royal icing (that calls for meringue powder) just fine. Meringue powder has sugar in it. Since you use powdered sugar in royal icing, it's fine. You can get meringue powder at Michaels or some other craft stores that sell cake decorating supplies.
