Choo Choo Train – 3 Sizes – 2 Options

Sizes: 4×4, 4×5 and 5×5 There are two options for this design. One with an underlay stitch and one without an underlay stitch. When to Use an Underlay Stitch. You should choose the design with an underlay stitch for most standard embroidery projects. Unstable fabrics: Knitwear, sweaters, and stretchy t-shirts need underlay to lock the fabric fibers in place. High-pile fabrics: Velvet, fleece, and towels require an underlay stitch to flatten the fabric nap so the top stitches do not sink in and disappear. Large fill areas: Big shapes and solid blocks of color need an underlay to prevent the fabric from puckering and shifting. High-contrast designs: Light-coloured thread on dark fabric needs a dense underlay to block the fabric color from showing through. When Not to Use an Underlay Stitch. You should choose the design without an underlay stitch for specialty or highly delicate projects. Ultra-light fabrics: Organza, silk, and sheer tulle will become too stiff, dense, and potentially tear if you use an underlay.
