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