If I am making a lot, I'll do the square sewn down the middle. I've not had luck with the method of using a bigger square and sewing so you end up with a bunch of identical HSTs. I am fine with trimming, so I will start out with slightly bigger squares so what I end up with is always exact.

When I want more randomness, then I'll use my easy angle just like sewbizgirl does.

me, too and here is a way to make 2, 4 or 8.

Here is my problem with the Block Loc.

I used the 6 1/2 Block Loc to square up two HSTs. One on the left is perfect, right one is no use at all. There is no marking on the ruler which groove side to use on the seam and both sides fit. So what am I doing wrong?

I have a love-hate relationship with HST's. I fell in love with a pattern and just had to make it. It turned out to be all HST's and squares measuring 2 inches finished. Needless to say, by the time I finished that top I was BURNED OUT on HST's. And I still am! For Christmas I made another quilt that needed HST's (for granddaughter) and I knew I had to find a way to make HST's easier than one or two at a time(remember, I'm still burned out). So I went searching. If I have to make more than 4 HST's,( and if you make quilts, who doesn't) I use the method that makes 8 at a time. I found a chart that tells you what size to cut the fabric for whatever size HST you need. And they don't need trimming!!!! Even my scrappies(is that right?) will now get HST's using this method. For me the wheel is now fixed.

I have the 8 in one. Fancy but is all in one so it makes it a little easier. http://www.ciscosewingsuppliesandnot...ngle-tool.html The chart size was online. I downloaded it and it's on the ruler. I have the WonderCut ruler and it's accurate. But time consuming.

Kitsie, I've had your diagram posted on the wall next to my cutting table since you first posted it. I refer to it all the time (since I don't trust my memory!). Thanks!

One thing I've discovered trimming 4-patches, when the ruler likes to slide where the seam allowances are pressed sideways, is to cut on a piece of batting. The unevenness in thickness seems to level out that way, and the ruler doesn't wiggle. I keep batting scraps for that purpose, and if you're clever (or desperate to save money, like I am), you can get several cuts out of a small piece by placing your block carefully. That could apply to trimming HSTs, I think.

Check their video on how to use the bloc loc. Works fine for me.
Still have to be careful how I trim. I find the way I stand is
important. I prefer to add a piece of clear Nexcare tape under
the small ruler to prevent it from slipping too much but otherwise
it works fine.

Just remember to put the logo "Bloc-Loc" on the low side of your
HST, i.e. the side where there's no seam. Here's another video.
Very simple.

I use Bonnie Hunter's essential triangle tool. Took a little getting used to but definitely saves material.
