Sarah Skirt Block
A block is a basic shape on which other patterns are based. They are sometimes also called slopers, although purists will argue that a block and a sloper are different things.
Blocks are typically not made as-is but rather serve as a basis for other patterns.
Designer notes
Sarah is the natural waist skirt block from W. Aldrich’s ‘Metric Pattern Cutting for Women’s Wear, 6th Edition’. Blocks like this are used as the basic shape of garment designs. This can be sewn as is for a pencil skirt. Though, there are more options available in Penelope. This is the first pattern I drafted for myself in different software as part of a collective attempt to learn CAD pattern drafting at my local maker space. (it’s the first in the book… probably not a coincidence). Several of the dimensions being magic and the curves being “what ever looks good” frustrated me intensely because they wouldn’t scale and the software does not contain a constraint solver to make up for that.
