Ooohhhh I found THIS video on how to use the CuttleBug too! I have received SO many e-mails from ppl asking me to do a tutorial on how to use this - it's been done AND it's in video!! Definitely check it out!!
Edited to Add:
I have used Big Shot Impression Plates on mine, and Fiskars Texture Plates work as well. FYI you need to FIRST get the Big Impressions Starter Kit (otherwise known as the BISK - it comes w/ 3 double-sided texture plates, a silicone rubber mat, and a flat base plate) to be able to use the Big Shot Impression Plates and the Fiskars Texture Plates - you can see that here (that's where I got mine!). You can see all the Fiskars Texture Plates here.
ETA to add - check out this post I did here to learn more about using the BISK.
I can cut through *lightweight* chipboard using the CuttleBug Dies. I personally do not know if you can use other die cuts (Sizzix, Big Shot etc) w/ this machine tho I have been told you can (I don't have any other brands so I can't say!).
I HAVE tried cutting through medium-weight chipboard w/ the CB dies - but the dies themselves are not deep enough - Big Shot makes deeper dies (called Thick Cuts) that are meant for cutting through chipboard and whatnot - someday I want to get a set to try out!
ALSO - Stacy left this comment on this post:
I just wanted to comment on the CuttleBug in case someone else had the same question I asked a few days ago in response to this post. I ended up purchasing the CuttleBug and a sizzix die. It will cut thin chipboard nicely :) I tried using a bazzill chipboard chip and it cracked the "B" plate so I'll stick with the thinner chipboard. I haven't purchased any BS dies so I'm still unsure about those. Hope this helps.
Thanks Stacy for your feedback!!
LeAnn also e-mailed me and said she's using the big Sizzix dies and Quickutz in her CuttleBug with no problems.
Thanks LeAnn for letting me know!
