Melissa of the awesome sewing blog Melly Sews has a passel of charming free sewing patterns, with so many that I had a difficult time picking just one to feature.  We chose this free men’s casual shirt pattern and tutorial, where she talks about how she used  a pattern-making technique called the rub-off, that she learned from the book Patternmaking for a Perfect Fit in order to make a bespoke pattern for her husband (and a Math gEEk shirt for her little brother.) We adore this photo of her seriously studious brainiac brother modeling his shirt, and channeling John Forbes Nash from A Beautiful Mind by recreating  mathematic formulas on glass.
