One of Ribblr ePattern's unique features is built-in interactive charts. You'll find interactive charts attached to instructional lines in a pattern - click the chart icon to open a chart. Click any cell of the chart to mark your progress. Your progress is saved and synced automatically. If you are not sure what a specific symbol in the chart means, click it in the list to watch a short tutorial video. Pro tip: if you are left-handed enable left-hand mode on your settings menu to watch left-hand stitch tutorial videos and to craft charts from left to right instead of right to left.
