My shimpagne was completely busted, but before I fixed it, I took a little aside and pressed it into an eyeshadow pan and stuck it into my 15 pan (lol, I had 3 eyeshadows at that time and I really really wanted to fill that pan). I thought of using it as an eyeshadow, but I actually ended up using it as a face highlighter, and it was so much easier too-I didn't clutter up my desk. I ended up pressing bits of my other msfs (I scraped a little off) into eyeshadow pans and using them that way in my palette.
I have to be careful so I don't take up colour from the other eyeshadows, but its really useful for when I travel. I only scrape a small amount each time so if it did crumble or shatter (which hasn't happened yet) I wouldn't be too sad.
I used 70% ethanol to press them. It doesn't ruin the texture of the msf. They actually end up being less dusty than normal.
