There are printable "thangles" on the internet.
I have the slider but since I don't FMQ I haven't really used it.
I have a light box but never use it. Usually my kids are using it.
I had a fusible sheet like the Goddess sheet and used it for placing my applique shapes before fusing it to my project. I use seam a seam now though, which is sticky and does the same thing. It is still handy for protecting my iron from fusibles but I usually can't find it and use parchment paper instead.
My machine is inset into my table w/ an insert so I have never tried the sew steady table. I used to want one when I had to keep my machine on top of a desk though.
I've heard nothing but good things about the mighty bright light. I opted for the LED lights instead and am happy with them, but they aren't aimable.
I am off to look at the Karen Buckley stuff...
