Sometimes you really have to do a scant 1/4" ... slightly (1 thread) less than 1/4", which over the width of the block will make a big difference.

Half square triangle. These are the blocks in the center of each side. I usually do flying geese instead of HST, but it depends on the pattern.

How short is your block? If it is just 1/8 to 1/4 inch short that is because your seams need to be scant. The thread and pressing take up some of the width.

Also, if this is for you and not a swap I wouldn't worry about it. Just make your border a little wider or add another row of blocks to make up the difference.

If you are using an electronic machine move your needle over 1 notch to the right to get your 'scant' 1/4 inch seam.

To test your 1/4 inch seam, use an index card. The lines are 1/4 inch apart. Put the edge of your foot on one line and your stitch should be on the one next to it, adjust where the line needs to be so that your stitch line is just inside the next line. That would be a scant 1/4 inch.

Good luck!

I love your block! When I make HST I usually make them a little bigger & cut them down to size. It takes longer but then they are always accurate. Works for me but not everyone wants the extra step.

Thank you. I will go back and try again!

That is so pretty. Are you using it in a quilt.

oneygirl

I think so. I will probably do a sampler with it. I have been trying diffrent blocks from a really cool online BOM. http://www.delawarequilts.com/BOMs/index.html
I just wish mine were as accurate as the directions on the site!

It's a lovely block and nice choice of fabrics.

When I make HST using the method shown in these directions, they usually come out small.
Try cutting your squares 4" instead of 3 7/8, then draw your lines and sew. You can always square them up a bit, but this may help you achieve a 12 1/2" block :D:D:D

oh! Thank you! I will try again!

make another block, but this time, use a mechanical pencil to draw your stitching lines on the back.
When your done with your block and it's 12 1/2", measure your seam allowances to see what your foot really produces and write it on a piece of masking tape and leave on your machine to remind you.
That is a beautiful block, by the way. I love pink and green :thumbup:

Went back and read the other suggestions. they sound easier than mine, especially the one about the three 1.5" strips.
