So my DH's firm was moving offices and getting rid of as much stuff as possible, which included a huge safe, a couple of drafting tables and stacks of vellum. Not blank vellum, but reams of plotter sized vellum printed with blue prints. Knowing what how much I would love to take possession of all these things, particularly the vellum, he brought them home to me and I went to work - on my fancy new (to me) drafting table [love!].

Spray ink, a die cutter and flower shapes is where I went first with this, layering the vellum with dress pattern tissue:

Vellum sheets work really well as a non-stick work surface too - not exactly heat resistant, but that could be fun too.
