at the hampton roads quilt show i saw the new martinelli slotted ruler. it has many slots, a lot like the june taylor one, it's measured off in 1/2's and it's made the same way as the one that only has one slot. it doesn't slide around and - are you sitting down? - it costs $89.99 at the show and will cost $119.99 online plus s/h when they get it there. it is brand new. at the shows they sell the small mat, the rotary cutter and the old slotted ruler for the package price of $199.99. i don't know if they will offer it online.
btw, the old one that only cuts only one strip at a time is selling for a mere $49.99 at the shows instead of $69.99, which is the new full price. it almost makes you want to run out and buy the new one at $89.99, doesn't it?
