Was it your sister's intent to coax you into doing it her way, or was it merely an idea? Thoughts from others can be good, but you have no obligation to take her suggestions. You might be selling yourself short and underestimating your creativity. Or you may be like me.....I love to quilt, but I don't have a creative bone in my body and I can't come up with original ideas at all, so I just look for pictures/patterns and follow them and just accept that I'm not creative, but that doesn't need to prevent me from enjoying quilting.
