You trace the pattern on the paper side(not the rough side)
cut it out and fuse it (Iron it )to the WRONG side of the fabric you are useing as your applique. let it cool a little and peel off the fusing paper and now you can iron this to your base fabric or background fabric. Hope this was helpful, can't imagine it did not have instructions with it, But we have all been there, so please dont feel that it was a silly question.
