I decided to try the acetone/thinner approach again with a different solvent and got excellent results.
- I used 'Cellulose Thinner'. The one I used was from Wilko, Cellulose Thinners 125ml £2.75

- Print your template using a laser printer (try and set the toner settings to 'Extra Dark' if you can)
- Stick your template face down firmly using tape so that it can't move and smudge
- Using a paint brush, apply a VERY minimal amount of the thinner to the back of the template, just enough to soak through. It's very easy to apply too much which will be too strong and create a blurred transfer.
- Using the back of a spoon, apply a lot of pressure, rubbing over the template several times.
- peel off the template and you should have a very clear, very sharp transfer
It took a few attempts to work out how much thinner to apply, but am very pleased with the results.
