I have a set of artificial flowers that I bought from Ikea.IMAGE LINK: https://flic.kr/p/2n4Q6pc Artificial Flowers

That's not the set I use now, but they're close. I wrap the stems together and use gaffers tape to keep them from coming apart. Set up as a group of three I simply rotate them until the color that I want is toward the top. I usually have them about 3 to 5 cm away from the subject. The texture in the flowers keeps the background from being completely even (even backgrounds look "flat"). For the Ladybug shot I was holding on to the Lavender stem with my non camera hand and I positioned the critter a few centimeters away from the flowers. The sky isn't bright enough at 6am to drag the shutter and expose for a blue sky, so I used the flowers.
