What size square should the finished HST squares measure please? I don't have the strip tube ruler but I do have the Fons and Porter HST ruler. First time using it and I believe you cut the HST's based on the finished square size. Thank you!

If we started with 3-7/8 inch squares, wouldn't they square up to 3-1/2" and the finished size would be 3"? Just trying to remember the math formula.

From Connecting Threads: The Formula: Finished Size of HST + 7/8".

The "finished size" would be once it's sewn into the block (i.e. no extra seams) so I'm going backwards. We cut 3-7/8" squares to make our HSTs according to Step 1 without the special ruler. SO, according to the formula above, 3-7/8 - 7/8 = the FINISHED size of the HST. When squaring up an HST, you square it up to FINISHED SIZE PLUS 1/2" for seam allowances.

Susie, that's why there are math people. I'm a chemist by education but hate math. Formulas are different, you plug in the numbers and use a calculator! Hahaha Thanks Roxana for doing the math for us. 😊

Nana told me last week the HSTs will square up at 3 1/2" which makes sense because we're cutting 3 1/2" squares of fabric as well.

Nana, I have a question about how many HSTs of background and fabric 1 we'll end up with. I've done the math twice and Penny's done the math and we both come up with 336... your instructions said 378.

Step 2 is open and there is a pdf file available. Have fun.

Nana, I am just following along but can't seem to locate the Step 2 pdf. Where will I find it? (Figured if I can't, others might be in the same pickle...lol!)

Never mind... Right after I posted this, I finally found it!!!

After reading over the step 2 I realized that I left some of the instructions out or assumed that you knew what I was doing. So very sorry.

Take 168 background 3 7/8" squares and combine them with 168 3 7/8" fab #1 squares to make 336 3 1/2 HST squares. You can do this by drawing a line and sewing on each side. Or use any other method you prefer.

Take 42 3 7/8" background squares and combine with 42 fabric #2 squares.

Take 42 fabric #1 and combine with 42 Fabric #2 to form 84 HST squares.

I hope this helps.... also your HST squares should be 3 1/2" to finish at 3".

If the above didn't help clarify or didn't answer your question please ask again and I will try to answer so that you understand. I am sorry but the original instructions left a lot out. I was rushing when writing these so that I could get everything to Mandy before her last day at QCA. I didn't proofread and mull over the instructions like I usually do.
