This is what I found out for you. It looks like yours fits . I would say its a MINIATURE.
Miniature Quilts
A miniature quilt is a scaled down version of a large quilt, with blocks no larger than 4”. Applique if present on a miniature is also scaled down from a full size version and also must meet the 4” block size. The maximum size is 24” by 24”. Borders should be correctly proportioned to the block and quilt size. Fabric selection must be appropriate to the size of the pieces and are usually small scale prints, textures, and solids. A miniature is not a small quilt with full size fabrics or blocks. A small quilt may consist of a single block or a number of blocks that are greater than 4” on any side, but do not qualify as a miniature. Miniatures are hung by pinning to the back drop so no hanging sleeve is required. No framed miniatures will be accepted.
