✂️ Finishing

Weave in all ends securely, ensuring no loose yarn tails remain on the inside that could irritate baby's delicate skin. Block gently by dampening and shaping to measurements if needed. Check entire hat for any rough spots or loose stitches. Turn hat inside out to verify interior is smooth and comfortable. If donating, wash according to NICU requirements before packaging.

🧺 Care Instructions

Machine wash gentle cycle in warm water with mild, fragrance-free detergent. Tumble dry low or lay flat to dry. Do not use fabric softener or dryer sheets as these may irritate preemie skin. NICU hats should be washed before first use.

Questions About This Pattern

Absolutely — just match the weight (Sport). You'll need about approximately 40-60 yards, so make sure your substitute has enough meterage. Fine yarns give delicate detail. Cotton is great for structured pieces; mohair adds a halo effect for a dreamy look.
This intermediate pattern assumes you're comfortable with basic stitches. You'll use ch, sc, dc, sl st and a few more (see the Abbreviations section above). If increases and decreases are new to you, a quick 10-minute tutorial on YouTube before you start will make the pattern much smoother.
Usually it's the joining or finishing — where individual sections meet and need to align. Read through the entire pattern once before you start so there are no surprises. Use stitch markers generously to track your place, especially in rounds. If a section looks wrong, count your stitches before proceeding — catching an error early saves a lot of frogging later.
For this pattern, gauge is "22 sc x 24 rows = 4 inches in single crochet". For decorative or non-fitted items it's less critical, but matching gauge ensures you use the right amount of yarn and get the proportions the pattern intends. If your swatch is too small (too many stitches/inch), go up a hook size. Too large — go down.
Machine wash gentle cycle in warm water with mild, fragrance-free detergent. Tumble dry low or lay flat to dry. Do not use fabric softener or dryer sheets as these may irritate preemie skin. NICU hats should be washed before first use. A general rule: when unsure about the yarn, hand wash in cool water with a drop of gentle detergent, squeeze (don't wring), and block flat to dry. This is safe for almost every fiber.
Each section builds on the last, so yes — follow them in order. That said, some finishing sections (like embellishments or optional edging) can be skipped if you prefer a simpler look. Read through all sections before starting so you understand how the pieces fit together and can plan your yarn usage across sections.
