Hmmm, I saw the challenge late last night but my darn allergies got in the way so I couldn't finish it. When I saw the LSC, the first thing I thought was a bowling ball...being a bowler myself (well, I use to be anyways). I finished the card today after I took a nap this morning after putting some Viscine in my eyes. But I think I don't think I followed the rules quite well either, but I was on a roll and went with it.
Here is my story:
When I saw the Limited Supplies Challenge and it was for The Circle of Life...meaning, making a circle card or to use any circles in your creations. You also had to use all the sentiments and stamps from one stamp set. Anyhow, I started with cutting 3 black circles from c/s with the cm cutting systems. I cut 2 smaller white circles for use of the inside of the card. I used another white circle for underneath the cutout holes for the ball. I placed one black circle c/s and adhered to the inside front to where the black would be solid. I typed the sentiment from the computer (word document) and trimmed to fit on the front of the card. I used the cb circles to cut the holes for the fingers. The bowling pins are stickers.
The inside of the card I stamped the RSVP information with black ink on the white circle. The sentiment is also from the computer in word document and printed onto c/s. I also added a bowling pin sticker.
In order for the card to open and close correctly, I scored 3/4 inch lines on black c/s, used the circle punch to make an accordian, and adhered with tacky tape.
I hope this works for the challenge even though the sentiments and stickers aren't from the bold invitation stamp set
