I used to do the sew through the paper method but discovered using either freezer paper or a glue stick and the original paper to make the "blocks" Start as you normally would any paper pieced block but before you do that use a tracing wheel to perforate the paper and make it easier to fold on the sew lines. Stick or iron ( FPM=freezer paper method) into place in the first section, fold back the paper, trim, add new fabric and sew next to the folded line. Iron seam, flip fabric, iron again and either glue or iron (FPM) second fabric in place. Fold back paper, trim, add new fabric and again sew on edge of paper to secure second block. Repeat to finish block then peal off the paper ( pattern intact and no ripping of paper) less bulk, easier to join centers, fewer error because you see what you are doing rather than obscured by paper and no mess! If you do not get this brief synopsis...try Utube and search freezer paper piecing. You might like the results even better than before.
