It sounds like you had a fun and creative project with your patchwork box! I have no idea with fabrics, but it's great that you were able to experiment and try something new. Taking the elasticity of the fabric into account is important for a comfortable and functional garment, but it's understandable that you wanted to use the patchwork piece in a creative way. It's always great to take on challenges like this and see what can be created, even if it doesn't always turn out as expected. Keep up the great work and keep exploring your creativity!
