2. Other Supplies:

- Scissors
- Measuring tape
- Pins or clips
- Elastic (optional, for securing the sheet)
Step-by-Step Instructions
1. Measure the Mattress
- Standard Australian Cot Size: Typically 70cm x 130cm. Measure the mattress thickness to ensure the sheet will fit snugly.
- Cut the Fabric: Add 2-3cm seam allowance on each side when cutting the fabric.
2. Cutting and Sewing
- Round the Corners: Trim the corners into a gentle curve to avoid sharp edges.
- Hem the Edges: Fold the edges inward by 1cm, pin them in place, and sew for a neat finish.
- Add Elastic (Optional): Sew elastic to the corners to help the sheet stay securely on the mattress.
3. Finishing Touches
- Binding: Use bias binding or fold the edges for added durability and a polished look.
- Label: Sew a small label in one corner to note the fabric type and washing instructions.
4. Washing and Testing
- First Wash: Wash the sheet with a gentle detergent to remove any dust or chemicals.
- Fit Test: Place the sheet on the mattress to check for a snug fit and ensure the elastic (if used) holds securely.
Tips for Success
- Fabric Safety: Choose fabrics free from harsh chemicals and suitable for babies.
- Secure Stitching: Ensure all seams are strong to prevent loose threads, which could pose a choking hazard.
- Regular Checks: Inspect the sheet periodically for wear and tear, and repair or replace as needed.
Why DIY Cot Sheets
- Personalised Design: Choose patterns and colours that match your baby’s nursery theme.
- Eco-Friendly: Use leftover fabric or sustainable materials to reduce waste.
- Bonding Experience: Making the sheet yourself adds a special touch of love and care.
By following these steps, you can create safe, comfortable, and unique cot sheets for your baby, adding a personal touch to their sleep environment. You can also choose from a variety of patterns and designs, such as scenic landscapes, adorable animals, and more, to create a unique and charming look for your baby’s bedding.
