This guide demonstrates how to draft a knit t-shirt pattern from a fitted bodice block pattern.

It covers converting the bodice block into a basic t-shirt shape, adjusting for stretch at the neckline and bust, and drafting a sleeve.

Additionally, it shows how to create an oversized t-shirt variation by slashing and spreading the pattern pieces.

Steps for Drafting a Knit T-Shirt Pattern:

1. Start with the back bodice block pattern and trace it onto paper.
2. Remove the center back neckline by squaring it off.
3. Redraw the armhole by going straight from the shoulder point to the underarm point.
4. Extend the side seam down by 4-5 inches for the desired length, going straight out.
5. Trace the front bodice block pattern.
6. Adjust the front neckline by raising it 2-2.5 inches higher than the back.
7. Curve out the side seams at bust level by 1/2 inch on each side for extra room.
8. Optionally, curve in the waistline by 1/4-1/2 inch for a more fitted look.
9. Draft the sleeve by tracing the original sleeve cap, then pivot it up 1/2 inch.
10. Redraw the sleeve cap to be 1/4-1/2 inch larger than the armhole measurement.
11. For a V-neck variation, mark the desired V-shape between bust and neckline.

Steps for Drafting an Oversized T-Shirt Variation:

1. Slash through the pattern pieces from shoulder to hem.
2. Spread the pattern by 2 inches at bust and waist levels (4 inches total at front).
3. Redraw the shoulder line by going straight out from the original shoulder point.
4. Drop the new shoulder line down by 2-3 inches.
5. Optionally, curve in the side seams by 1/2 inch for shaping.
