No, sorry plans have stalled this week as I am broke as hell due to keycaps. Also I haven't heard back from inquiries to a few foam providers -- lame.
The person doing the sewing will also be gone for a bit on a couple of trips, but we haven't forgotten about the project... but if you're in a hurry to get a sleeve then you might wanna look elsewhere.
You know how these things go... GLWIC.
