Cool Fabric!

in this case (let's say 5 yards.) how big a finished product are you talking about? nobody seems to be able to say what the ratio is between yardage and finished product, even approximately.

I have wanted to use outer space fabric for a obw for a long time. I have several yards of one -but I prewash and you aren't suppose to do that for obw's... I bought it at Joann's when I was up north... but our Joann's is opening Friday! Yay! I am crossing my fingers they have the one I want to use :)

That will make a fabulous one :)

Regarding the size of the completed quilt: well, that's a good question... It depends on how big you cut the triangles and lay out the completed hexagons. It will be less than you think because there are lots of seams. I'm guessing that it will be a largish throw, about 60X60, but it is really variable. If you get 5 yards, you will probably have about a yard left over you can use for borders or a piece you can add to the backing. You can cut the triangles any size, but I think a good size is under 4", like 3.5 or 3.75. Just make sure you use a 60 degree ruler to cut equilateral triagles (measure the same on all 3 sides)

I did a throw, then enlarged it to make a twin quilt with borders from a OBW patttern and needed 4 yards with a 10 inch repeat.

okay ;) somebody willing to comment on the size issue!

i was THINKING about what it takes to do a ....let's round up to 100 x 100.
at that size, i wouldn't dream of small hexes. and i think that size can take large ones. so in the range of finished 10" at the widest measurement, what would you GUESS (this is not a test) is the amount of yardage needed? bigger hexes = fewer seams.

at the other end of the scale, what would you think at 6" finished at the widest?

I personally think too large of hexagon wont be as pretty I think The 6 would be better....

I agree. Based on the size of the penny relative to the planets, I also think 6" would be better. So cutting the strips around 3.5" or 3.75" should work out fine.

The final size of the hexagon doesn't have to be an established (even) size ....just as long as all the strips are cut the same width.

i think that would be great

The bigger the hex's, the less contrast. Did you see k3n's post where she used three different sizes of hexs of the same fabric? Here it is.

BFW, here is a quote directly from the OBW book:

"How much fabric should you buy? There are very few rules, but there are some guidelines. The size of the quilt depends not only on how much fabric you buy, but also on how many hexagon blocks...you eventually use in the quilt...(and) on how you arrange t he hexagons and on the shape of the finished quilt. To make a good lap-size, twin, or full-size quilt, 4.5 y ards for hexagon blocks or 5.75 yards for octagon blocks is enough. For a queen size or larger quilt, double those amounts to 9 yards for hexagon blocks or 11.5 yards for octagon blocks.

Measure the repeat. If the (repeat) is 6" to 8", which is a short repeat, the fabric will produce a very small project. Larger prints usually feature a repeat about every 24". This is the type of fabric I typically choose. Four to five yards makes a very comfortable lap quilt, and depending on the borders used, it can grow to almost any size.

For Hexagons: 6 repeats at 24" each is exactly 4 yards...Add an extra half yard or yard (4. 5 or 5 yards) to have a piece of the original fabric as a reference."

BFW, I probably wouldn't recommend cutting strips any bigger than six inches, and I'm not sure that wouldn't be too big. It would depend on the print.
