I've noticed some loose bits of thread coming off my kite particularly along the LE and down the main seam in the middle. I think it's just bits of fabric unravelling and not thread holding the kite together. Is this normal/ should I be worried...?
If it's the thread from the zig zag stitch then Yes it's a problem and would need to be re stiched , cheaper now than if it lets go and causes a tear right through your kite . If its the end of the kite material after the stich then it's normal don't worry about it . And if you kite is an older one might be time for a new one !!
second and third photo just look like the edge of the kite material unweaving - nothing to worry about...just snip the unravelled material off with a pair of scissors.
the first photo its hard to tell if its kite material or the stitching. if its kite material just snip it off, but if its the stitching get it fixed now by a professional repairer.. Steve
