A size 18 or 20 blunt tapestry needle works for most waxed linen and cotton thread. Pick a needle whose eye is wider than two folded thread strands, so it passes cleanly through each hole.
Do I really need a bone folder?
Yes — a bone folder gives you sharp creases without shining the paper, which a fingernail or pen cap will. For 80–160 GSM paper a 6-inch real or synthetic bone folder is enough.
What is an awl used for in bookbinding?
An awl punches clean, pre-marked holes through folded signatures so your needle slides through easily. It keeps holes aligned across signatures, which is what makes the spine look straight.
Are these tools safe for children?
Needles and awls have blunt tips suitable from age 10 with adult supervision. Cutting tools (rotary cutters, craft knives) are 14+ only and clearly marked on the listing.
