You can use the usual sprue, or use fishing line. The line I used was only about 1LB and was a bit thin for 1/48, but for 1/72 it should be ok. I'll get some heavier line when I'm in town.
I just pushed the end towards the candle flame and it mushroomed over perfectly. I pressed it through the hole in the wing and added a little 'Superglue' to the sprue under the head. It pulled nicely into place leaving the head showing. I pulled it into the other hole and added a bit more glue. I hung a set of clips onto the sprue while it set and then just trimmed the tip off. The little head can then be trimmed off flush and pained over. The fishing line worked well, though some sprue may snap, not being as flexible or as strong. It also makes nice rivet heads for various uses. Just drill into the plastic and then drop the rivet right through. Cut it off under the plate as required.
Using sprue on the straight wires works well. The angled ones are best done with with the fishing line.
Here's a little sketch. ( Just like the ones that Stan Catchpole used to do. Remember him ? )
