The easy way to show a huge picture in church is to put it in a
computer and project it onto a screen. This used to be quite a pricey business,
but now it's possible to buy the equipment and hardware quite cheaply, and most
churches have a nerd boy somewhere who will know how to transfer an image from
a computer file or bit of paper to a PowerPoint slideshow.
Rule number one for pictures on bits of paper: make them as large as possible. If your church has up to 100 people, the smallest size you should work with is A1 (594 x 841mm). Even this can look a bit titchy, and it's really best to use much bigger pieces of paper. With larger congregations, huge pictures are essential or the people at the back won't see them. When I used the picture of Rodnus Roman (on the full armour of God page) I made him about 2 metres tall.
Where do you get such large pieces of paper? Well, I'm a structural engineer and in the office we have big inkjet plotters for printing out our drawings. Once we bought a new plotter and the rolls we had used in the old plotter didn't fit so I picked up loads of paper that would otherwise have been thrown away; sometimes I just ask if I can have a few metres. If you know an engineer, or an architect, or someone who works for a printer, you could probably get hold of large bits of paper just as easily. A less satisfactory source is lining paper - available from DIY shops - but the rolls are only about 600mm wide and it's usually cream rather than white. It's cheap and it looks it.
The easiest way to draw a large picture is to start with a small
one. Draw it on a bit of A4 and make sure it looks right. Hold it at arms
length and consider it with sober judgement. Ask someone you trust what they
think. When you have stopped arguing, grudgingly make any changes they suggest,
scan the picture in to a computer, stick your big bit of paper on the wall and
shine the picture onto it using a projector. Go over it in pencil, turn off the
projector and check whether it still looks OK. Then, using a big fat marker pen
and long flowing lines, ink over the pencil lines. If you use a thin pen nobody
will see your picture, and if you use short lines it won't look good. Colour in
the picture with poster paint if you wish. Remove the paper from the wall and
replace the wallpaper because the marker pen has soaked through and won't come
off. Resolve to stick a bit of polythene up first next time.
