One of our windows needs repairing, but I can't for the life of me find a piece of wood to replace the rotten piece. I have narrowed it down to "glass bead moulding" but can't find it in this size, which is roughly 40x30mm. I also don't need 2 metres of it which seems to be the only length anywhere sells
but I'll take that if I can find the right size. Any advice please?
