Here's a Crochetology challenge: use an existing skirt pattern to make a top-down seamless cardigan.
The skirt pattern I used is from Drops Design, and it is a beautiful free pattern with very straightforward shaping. The pattern consists of alternating rows (or rounds) of tr-groups and hdc-ch stitches. Observe the pattern below, in symbol.
The challenge is to modify this pattern so that I may have increments of inc/dec to shape a cardigan. To determine how much shaping and where shaping is needed, I divided the cardigan into several sections, namely:
Below are photos of the progress of the cardigan. More detailed documentation is given to Subscribers of Crochetology. If you are an experienced crocheter, you should be able to take on this challenge and come up with your own designs.
Below are two other design variations, both using the same basic stitch pattern of tr-groups and hdc-ch rows. The first one has shorter sleeves and a wider collar. The second one is sleeveless and shaped to be narrower at the shoulders. This second design entailed more complex shaping and dividing, the Left Shoulder and Right Shoulder sections being worked separately from the back in order to achieve the narrower shaping.
