Another option for stencils for using with your bullet journal is metal drawing tools. These provide a firmer framework than using plastic stencils and can also double up as a ruler/measuring tool. They are also slimline so that you can use them on the go if you need to.
Again these templates are suitable for bullet journalling with a range of useful icons suitable for using with your diary or planner.
When choosing your stencils – it is important to have a think about the icons that you will need and use so that you can get the most out of the stencils you have chosen.
