I have to say, I have searched and tried various papers but Swedish tracing paper wins.
Swedish Tracing Paper is a paper-like material that allows you to modify your expensive paper patterns without cutting into them. Making clothes for a friend or a growing child? Trace pattern pieces into multiple sizes!
A soft and translucent paper, resistant to tear but easy to see through, making it excellent for copying the detail from existing patterns.
- Ideal for taking copies of delicate tissue paper patterns
- copying a pattern to use in multiple sizes
- making alterations to existing patterns
- or making a pattern from a piece of clothing
I found one company where you can get it from in the UK, they provide very good service too. You can access their online shop here.
