Ribbuild is a powerful tool for designing new patterns, but you can easily add an existing PDF pattern, too, using our quick copy & paste feature. Simply add a new pattern on Ribblr, copy multiple lines from your existing pattern, and paste them directly into a line in Ribbuild. Ribbuild will automatically detect, split, and apply formatting to your lines, including row/round numbers. Note: we recommend copying patterns directly from the original file. (Word, Pages, InDesign etc.)
