Don't Iron Stencils

I purchased stencils at MQS. The lady who sold them said I could iron them on a wool setting and flatten them if they needed it. I tried it. Good thing my iron has a Teflon bottom, and this stencil is long enough that there is a big portion still useable.


Maybe she meant a different setting than wool. Maybe my iron gets hotter than hers, or maybe I misunderstood……
