For something that size, you can probably get away with a good quality sail tape or pre-cut patches. Some kites come with a few pin-prick patches that are simply peeled off and applied to both sides of the hole. Otherwise, buy a roll of sail tape from your local chandlery and neatly cut a piece to go either side. Make the patches about 10 times the diameter of the hold and try to avoid rough cut edges as they are more likely to peel off than smooth cut. If you can cut a roundish shape in one smooth cut then you won't get corners so you can press them nice and flat to the canopy.

Clear repair tape will fix those no problem, nice pics! :-)
