A square neckline is a classic feature of a peasant-style blouse. Whether you opt for a square neckline to create a different look or make your blouse more flattering, a square-neck peasant blouse pattern is quite simple to draft even if you have limited or no pattern-drafting skills. Once you've completed the blouse, adapt your newly drafted square-neck peasant blouse pattern to make nightgowns and even dresses.
Trace the front piece of your peasant blouse pattern. Add or remove fullness at the centre front of the pattern piece if desired by extending the lines at the neckline and hem. Compare the pattern piece to a blouse you already own and like or hold it up to yourself to judge fit and fullness. Cut the pattern piece out as a rectangular block to make it easier to alter for a square neckline.
Decide how low or deep you would like the square-neck peasant blouse, holding the pattern up to your chest as a guide. Mark the centre front of your pattern piece at this point. Create a modest square neckline suitable for an adult or child by marking a point 2-1/2 inches below the collarbone. Choose a lower and wider square neckline for a dressier peasant blouse.
Lay your peasant blouse pattern down flat. Use a straight edge to draw a line across the pattern piece at your neckline marking.
Measure 1/2 inch from the edge of the shoulder (adjust appropriately if your pattern allows for a different seam allowance, like 1/4 inch or 5/8 inch). Draw a line from the shoulder marking to the neckline, perpendicular to the line you just drew.
Measure 1/2 inch in from your marked square neckline and draw these lines into place to create the cutting lines for your square neck for a peasant blouse.
Bias bind the neckline on your square neck peasant blouse for a neat and comfortable finish.
Keep in mind that a peasant blouse is typically gathered. Your square neckline will look quite rectangular on the pattern, but will be square once the centre front of the blouse is gathered.
