Zippered pouch
 

My daughter is wanting me to make a zippered pouch 10" wide, 6" high and 6" wide. I've drawn pictures and used scrap fabric and I just can't figure out what size to cut the fabric. I tried a 19" square but when I make the box corners I end up with maybe 6" X 4". Tried a 19" X 22" piece and have the same problem. Is there some kind of formula to use?

I don't know of a formula, but the initial rectangle has to be big enough to allow for the 6" dimensions. Maybe use some scrap fabric or paper to experiment with sizes of rectangles to have enough fabric for the 6 inch width, and then add on enough paper/scrap fabric to achieve the height, then you can take it apart to get the right overall rectangle size.Does that make sense? The 10" width is the easy part!
I sort of assumed you are using the technique where you make a triangle at the corners to achieve the box end.

I suggest doing a "google" there are hundreds of tutorials on zippered pouches.

Melanie Ham has a great tutorial for a zippered box pouch. I've made a few of them and there a good size.

It might be easier to buy a pattern.

Watch for the sales at JoAnn's or Hobby Lobby.

I'm thinking a rectangle about 17 x 25 might work.

Logic for that guess: 10 + 3.5 + 3.5 for the width. (10 inches plus 3.5 on each end for boxing)
6 + 6 + 6 + 6 = 1 for the circumference plus the allowance for the zipper.

Ou-I see you're wanting box corners.

I believe she also has a tutorial for that as well.

This is a great tutorial and pattern! I recently made these from it for my daughter who needed knitting project bags. I added pockets to the inside and also used pre washed flannel as a stabilizer quilted to the outside fabric before assembly, to give the bags a bit of body. It's what I had on hand. Worked well. The pattern includes 3 sizes and the measurements.

The noodle head pouches are great but not exactly the size your daughter wants. The largest has a finished size of 8.5″ H x 8″ W x 4.5″ D not quite the requested size. I am very curious as to why she has such specific dimensions? Is there something specific she wants to store in it? Or is it just an arbitrary size she has "determined" that she wants? My daughter doesn't sew at all but she will sometimes say something like.....I want a table runner to be 10" wide and 42" long. When I ask her why, she doesn't really know, just that is what she "thought" table runners should be! We go from there to determine the best size for which table she plans to use it on.
Makes life much easier.

Does she want it in the boxy like the shape of a large tissue box or like in post #9?

She wants it boxy. It's for a baby carrier. I could have bought it for $29.95 but she wanted me to make it. It's driving me nuts. I think I might have found the answer but still not completely sure. https://www.trulymyrtle.com/blog//20...-tutorial.html

How about this pattern?

Jenny with MSQ has good tutorial on youtube called "The Zipper Pouch: An Easy Quilting Project Tutorial by Jenny Doan of Missouri Star Quilt Co" .

Not sure why you are ending up with 6x4??? Cut a 19" piece and fold it in half then you should press a good middle bottom seam. When you make your box corners, the side seam meeting the bottom press mark and sewing scant 3" to each side of the seam should give you a 6 x 6 x 6 with 1/2" at the top (on both sides) for the zipper area. The width of your fabric should be 17" to allow for a 10" width and 3" on each side (making for a 6" depth) with a 1/2 seam. (Whenever I make purses, pouches or similar items, I like to use 1/2" seams because I double stitch for extra reinforcing.) The only thing I can come up with is that you are accounting for the correct size for height and depth, but not for the width. To restate - your piece needs to be 19" by 17". Please let us know what you figured out.

The impression I got from the original poster was that the daughter wanted it boxed on top and the bottom.

So - if she does want it boxed on the top and the bottom - that would be 6 + 6 + 6 + 6 plus 1 inch seam allowance for the circumference by the needed width - which I agree that 17 inches would work.

Yes just like this. I'm pitching the piece of fabric I've worn out and starting over. I'll try 17" X 25". Wish me luck! Thank you everybody.
