I'll take 70 cm for each string and i done 5 repetitions of the pattern, resulting a 15cm bracelet. More than enough for an adult wrist. Maybe better taking 80 cm for each string to finish better.
You might also benefit by cleaning your lens with a soft cloth @Cookie323 🙂 And yes, I agree with @halokiwi that the best results from taking are usually on nice sunny days with lots of natural light. We have guidelines that we follow when accepting photos, and some mods may be more lenient with photos than others. It's nothing personal when a photo gets declined 🙂 When you spend lots of time and effort making a bracelet, we want other users to be able to see it as best as possible 🙂 Some of your pictures do look a little bit cloudy, which is probably just from fingerprints on your device's lens. I personally might have declined some of them too, but again, it's nothing personal at all 🙂
@Cookie323 I looked at your photos and many of them seemed fine but some were indeed a little blurry. The reason seems to be bad lighting. If there isn't enough light a camera can't take good pictures. I recommend taking pictures during the day when you have the sun as a natural light source.
