LACING ON THE BOOK

LACE BOOK

For many years engaged in bookbinding business. Stapling the sheet sets at the root, not sew them, string, inserting in the cuts the block with a depth of 3 to 4 mm sturdy thread in the shown sequence. Then coat the lace with glue— everything works faster and stronger.
