I actually have the big kick you can use the cuddle bug dies with it.
I use blended wool felt, it's less expensive then the 100% felt. I buy it on line.
Some are 30% wool some are more. I really like the flower shaped buttons. I think they were 2 for $1 at Hobby Lobby in the fabric section. I have made some other flowers with larger dies that came out well. You could try those as well.
Here are some others ones I made with different button so you can see the difference. I also sometimes cut the flower layers and sell them on Etsy but my last ordered destroyed my cutting pads so once I get more in I put some in my Esty store.
