Top tips for Disco-Dave with regard to card modelling.
Don't try and economise on blades for cutting, as soon as the keen edge has gone replace the blade. You don't have to use expensive craft knives if you can't afford them as the cheap Chinese imports of plastic knives with the snap off blades are fine for the job.
A strong steel straight edge for cutting, never plastic or wood.
The new self healing cutting boards are quite good as a surface to cut on but my preference is plate glass. My work table has a sheet from an old coffee table but in the past I have used a car window from the scrap yard. Glass is also very good for putting blobs of glue on to work with as when it dries it is easily scraped off with the short end of the steel straight edge and best of all it is perfectly flat for testing your models on.
Don't use cheap cardboard with a high soft fibre content as this soaks up moisture from the air. The card should be really 'hard'. I used to get my basic building card, when living in the UK, from a local printers outfit. Quite cheap in big sheets. Art shops sell good quality card as well. Photographic mounting card is also good, if quite expensive.The finer card for detailing I get from filing cards, post card, old Christmas card and even old medicine boxes. It's suprising what good quality card some manufacturers use for their products.
I believe that white PVA glue to be the best all round stringless adhesive to use.
Shellac is very good as a preservative for card and a damp proofer if your circumstances dictate the need. Shellac is also sold as button polish. I buy mine as brown flakes and melt it down with methylated spirits.
Don't be tempted to use over thick card as it isn't necessary, unless the scale you are working in needs it of course.
Some of my card models are over half a century old and still as good today as when they were first made so don't let people tell you that card models don't last.
That's enough to be going on with Dave and if you need any further help then just ask.
