Bottom-Up Knitting
Bottom-up knitting is the traditional construction method where a sweater is knitted from the ribbing upward toward the shoulders, often in separate pieces.
Explanation
Bottom-up is the classic way to knit sweaters: you start with ribbing at the bottom of the body and sleeves, knit upward, and finally shape the neckline and shoulders. The method is often worked in separate pieces - front, back, and sleeves - knitted individually and sewn together at the end (finishing/seaming), but can also be knitted seamlessly in the round up to the underarms. The advantage is full control over length from the bottom up, while relying more on gauge and calculation for the pieces to fit together.

How the garment is built
You begin at the lower edge of the body, work up to the underarm, knit the sleeves separately from the cuff up, and join everything into a yoke or raglan shaping toward the neck.
This is the traditional construction, and most older patterns are written this way.
Advantages
The lower edge is finished immediately and you do not have to decide the length last. If you run short of yarn, you find out early — the body is the part that takes most.
The drawback is that the garment cannot really be tried on until body and sleeves meet, and adjustments at that point mean a lot of ripping back.
Common mistakes
- Discovering a fit problem only when body and sleeves are joined.
- Working the sleeves one after another and ending up with different lengths.

Frequently asked questions
What is the advantage of bottom-up?
You find out early whether the yarn will last, and the lower edge is finished from the start. Most traditional patterns are written this way.
Can I try the garment on as I go?
Only partly, until body and sleeves are joined. That is the main drawback compared with top-down.
