Looking for a "sipping" lid for my double-walled SP600. Fired off an email to Don at Four-Dogs asking if his lids would fit the double-wall (which, upon further research here, I think they do), but I haven't heard back from him (five days or so).
Is he still producing lids?
Any other sources for a good lid for the double-walled SP600?
Help me keep my tea warm this winter! :)
