I have made a couple of autumn cards, so I'll share those with you:
Both of these cards use a leaf set from The Angel Company, which is my favorite autumn stamp. I have had this set for 5 or 6 years, so I'm not even sure if they are still available. I used alcohol ink for the colored background, then stamped my favorite leaf stamp. On the first card I just cut the stamped background into squares and put them on the card. I used some fibers I've had for some time. (Just trying to get rid of stuff).
On the 2nd card I made the background the same way, colored it with alcohol ink, then stamped the leaf. I punched this set out with a scalloped punch, and tied raffia around the background.
I hope you have a great week, and I hope you get to do something crafty.
