I am so excited about this project. Super simple – you only need to take 3 measurements and a little bit of primary school maths and you’ve got yourself one great pattern piece. Aces, right?
Read on to find out more on how to make your own DIY t-shirt pattern.

Killer guide to making the ultimate DIY t-shirt the pattern
You will need:
a roll of paper (wrapping paper, brown paper, newspaper will do)
1. Take your 3 measurements: bust at its fullest point, shoulder to armpit (best to keep this measure on the long side), shoulder to waist (or where you’d like the t-shirt to finish).
2. We’re only going to create a pattern for 1/4 of the t-shirt. The longest edge of the pattern (the side without the sleeves) will be placed on a fold of fabric to create a whole side of a t-shirt. So now it’s time for a bit of primary school maths.
3. Divide your bust measurement by 2, then add 3 cm (1 inch) for seam allowance. Add 3 cm (1 inch) for seam allowance to your shoulder to waist and to your shoulder to armpit measures.
4. Now mark out your pattern using your measurements. Start by marking out your bust measurement and shoulder to waist length. Turn those into a rectangle. One half of the rectangle should be the edge of your paper. This will be your centre fold (more on what that is next week).
5. For the ‘sleeves’ mark out your shoulder to armpit length. This will be the opening for your sleeves. I went for shortish sleeves so measured out a rectangle that measured 11 inches tall by 4 inches wide (27 cm x 10.5 cm). This rectangle will start from your shoulder and end at your shoulder to armpit length.
6. To create curves I just freehanded it, but you could use a ruler to help you keep it uniform. Or a compass. I like Charlotte’s tip on making sure curves on the fold are at a right angle.
7. To make the neckline I free handed it again, but you could measure this out, or even use a favourite t-shirt neck as a template.
