This card is for 4 challenges:
1. Splitcoaststampers Clean and Simple Challenge - CAS160 - use a monogram;
2. Freshly Made Sketches - FMS24 - sketch;
3. Pile It On Challenge - PIO10 - spots and/or stripes; and
4. Less Is More - Week 57 - Colours - neutrals.
The stamp is a Martha Stewart set. The rest is pretty self-explanatory.
