Suite101 – Choosing a Paper Trimmer

Size – Smaller paper trimmers are best for crafters who are on the move and pack their tools into a tote bag. Scrapbookers who attend crops may want a small trimmer. Alternatively, larger paper trimmers are more stable and provide more accurate cuts. Larger trimmers also generally have higher quality blades, which stay sharper longer. Also, crafters who work with 12 in. paper sheets will require a paper cutter that has a cutting length of at least 12 in.
