Yes! After you indicate the sizes available in your pattern's introduction section you will be able to apply specific sizes to each line of your pattern. Simply tap on any line, and click the 'Sizes' option in the toolbar. Finally, tick or untick the applicable sizes for each line. You can also select multiple lines and apply the same sizes for multiple lines at once. Crafters who follow your pattern will only see the lines that apply to their chosen size, as part of our smart sizing feature.
