Tap on a spool of thread from the pins in the lower section to move it into one of the active slots above them. Drag the thread from the active slot up to the corresponding colored section on the knitted pattern. Continue this process until the entire pattern is filled with the correct colors to complete the level.
Each spool has a limited amount of thread, so use it wisely. Some pins hold multiple spools of the same color, indicated by a number. Pins with a question mark contain a spool of an unknown color, which is revealed only when you select it. You must use the spools in the front rows to access the ones behind them.
Begin by filling in the sections with known, visible colors first. Use the process of elimination with your remaining spools to figure out the colors for the pattern sections marked with a question mark. Strategically clear columns of pins to access the specific colors you need for the pattern.
