The parcel was from Station Road Baseboards. Impressive service - next day delivery. I found them quite by accident Googling for clear plastic sheet to try out the new (to me anyhow) window frame technique I'd read about on Iain Robinnson's blog.
Anyhow, progress on the chapel. Using plasticard sheet, fiddly bits of plastic strip and Milliput filler I have just about completed the window surrounds. A bit of filing and sanding down tomorrow once everything is properly dry. It's a reasonably pleasing overall effect but close inspection shows up unevenness of some of the surrounds. I now have a neck and headache.
