I've read lots of discussion recently about pros and cons of these cutters and while I'm not trying to convince anyone to buy one I thought I'd address two here.
One con is that you still have to precut and you might as well just do all the cutting yourself: My answer is yes, for the Kaleidoscope blocks, I had to rough cut 7.5 inch squares - that was really quick....much quicker than cutting all these triangle shape pieces. In some cases, you can just fanfold your fabric over the die without cutting too.
Rolling through..... I'm typically cutting 8 layers at a time ...that's 16 of these triangles I get with one quick pass. I couldn't begin to cut them this quick.
Another con I've read about is about wasted fabric. These triangle shaped leftovers will go into my crumbs and string bins so they don't bother me...it might bother you - I don't know.
Now, to my question for today. How perfect is your piecing? I've been fiddling with these blocks and some are better than others but the funny part is the more I TRIED to get them perfect the worse they were so I went back to my usually method of pinning which depends on feeling and manipulating the seams with my fingers and then using pins to hold it in place. I tried the pin through the middle of the seam and even tried basting the center in place first (easier to pull out if it's off) but the blocks I tried those on were worse.
Most of the blocks look like this and I'm NOT showing closeups of the bad ones!
Not sure where this top is going - the fat quarter packs I started with are small ... and I pulled one fabric from stash that works too (12 blocks total at this time) but I'm going to have to border them with something. I think this fabric has too much green in it.
