Strider - Nice job on the cape! Only things I procured thus far from eBay is the Wookie Braids (which I still need to work on) and a US Army Half Shelter for the Cape! For the cape, the material didn't have the correct stitching so I too it to an alterations place with the 501st CRL Pic. The alterations lady laughed at me when she saw what I was looking to do, but said that the stitching could easily be done. I told her that I'd handle the putting on the grommets and ripping and weathering of the cape and that all that was needed from her was exact stitching. My dimensions of the cape (Since I'll be a 6' 2" ROTJ Boba Fett) will be 48in Long & 29.5in Wide. For that plastic piece, if you don't mind my asking, what did you end up using?
Thanks! My part of the shelter wasn't the correct one either as it was from a buddy who used the right part ;-) But the stitiching is really easily done. I didn't take exact measurements as I simply went by fitting it to my height.
You can really use anything with the appropriate thickness for that piece as it's painted anyway but I used 2mm ABS plastic cut in shape.
