    Does it sound right that out of a 45"wide fabric, I can get 60 5"x5" squares from 1 yard?

    Only if it is truly 45" wide fabric, usually I figure 8 squares per row (or 9 if it is 45", if you only get 8 per row, you will get 7 rows in a yard or 56 squares. Hope this helps.

    Assuming it's 45" and that you can cut 5" without waste, you can get 9 squares (for me, I'd get 8). I would conservatively plan on 8, but, yeah, 9 if you're really really precise.

    1 yard = 36" = 35" -> 7 squares (assuming it's a full 35". Some of the pieces I get are cut really askew and I lose more than 1").

    So really conservatively, I would say 48; conservatively 56; probably not going to happen but theoretically possible 63

    NO. YOU NEED TO REMOVE SELVAGES AND STRAIGHTEN THE CUT ENDS YOU WILL BE SHORT.

    ok, please check my math for this LOL I suck at math but I think I got this right:

    I need 60 5"x5" squares. 45"wide fabric adding in a little for error - I should be able to get by with 1.5 yds

    I need 15 - 12.5" squares - same width as above, 2 yard should do?

    Also, 60 - 6.5 squares, 2 yds should be enough? same width as above.

    Thanks for your help!

    You should be ok with those yardages. Cut carefully.

    You've got good advice from everyone here. You really need to check your width less the selvedge. You'll probably find that you'll just get 8 cuts across. You should get 7 down the length as you have 1" to play with, but do check carefully.

    What is it they say - measure 2x (or in my case 3x or 4x) and cut once!

    Lots of fabric is less than 45" these days, so you need to check that out first.

    OK, now we need to know what you're making! :lol:

    Cool. Something I can contribute an answer to. 56 squares. Math is more my thing than color and stuff. I have found that some patterns aren't really 45 inches. The 45 inches includes the selvage. Depending on the pattern, how well it is printed etc, I count on 40 inches and anything else is bonus. With that in mind my calculations tell me that you can get 8 squares per row and 7 rows per yard.

    I admit I'm very new to quilting, not to sewing and definitely not math.
