Thank you for viewing! My child wore this 2 or 3 times, but there are no noticeable stains or fuzzing! The recommended size for use is around 6 months to 1.5 years old. The yarn stretches and shrinks to some extent, but we recommend using it within the recommended size range! Since this is handmade by an amateur, there may be some imperfections in the stitches, or it may be different from what you expect. ⚠️ I take the utmost care when making these, but please refrain from purchasing if you are looking for perfection or are not fond of handmade items.
