title: Bella Fabric options
If you are making a test Bella to see how it fits we recommend a fabric such as **Calico (Muslin)** or a cheaper fabric that matches the drape and stretch of the fabric you intend to make a pattern based on Bella with.
<Note>
###### Bella is a block, not a pattern
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.
