I like variety. Here are the things I look for:
- Flowers (non repetitive CU)
- Unique non-flower elements
- Foliage/leaves
- Ribbons/bows
- Cards
- Banners
- Frames
- Tags
- Brushes / paint splatters / stamps
- Scatters
- Buttons
- Fasteners: staples, stitches, etc
- Word art
- Beautiful patterned papers
- Complementary colors
- Theme (I like versatile kits)
