[Mithalwen]

In UT it says that he "never made for himself any lasting abode" and that he dwelllt in no place and gathered neither wealth norfollowers. It also says that he travelled mainly on foot. However we know that at times he has use of a horse and horse and cart. We also know that he made fireworks which I suspect is not something even a wizard finds convenient to do on the road. We know he borrows horses from Elrond Beorn and Rohan and while he seems to be received in mortal lands as a guest at Rivendell he seems part of the househol while he is there and while we don't witness it he no doubt is equally welcome at the Havens and Lorien. Cirdan instantly recognised Gandalf's significance as shown by his passing on of Narya to the one who seemed least of the Istari. Cirdan as Lord of the seemingly mose craft orientated elven realm may well have provided workshop space to Gandalf.
