Do you use these? Are they a good investment? Are the ones at Aldi a good place to start (cost-wise?) I have been using parchment, but am considering switching over.
TIA!

I use them and love them. They are also good for rolling fondant and gumpaste on.

I just got the one's from Aldi yesterday and I bought it for baking and cookies but I then realized they were great for rolling fondant instead of the wilton rolling mat because it sticks to the table. So I think you should definitely invest in some!
