Quick and easy “Doubly striped Half Square Triangle block” (Hidden wells)

Easy block tutorial - from fabric strips to quilt block

This block can appear to be a bit complex at first sight but it’s quite simple to do. All you need is 4 strips of fabric the same size sewn together. Use high contrasting fabrics for better results. My choice of fabric makes this block a bit hypnotic, don’t you think?

Some ideas for extending this block

This block can be made into a scrappy quilt by using your fabric scraps or jelly rolls. I do find however than this block works a lot better, and I mean A LOT, if you plan your fabrics and colours.

Colours

For instance, use fabric that are high contrast and alternate them:

  • acqua and black,
  • red and white,
  • red and black,

actually any light colour and black or white would work well.

Use only 2 fabrics, one print and one white or black.

Try with solids. Black and white would look great.

Use complimentary colours or interesting colour combinations. Checks, strips, polka dots, types of fabrics work great.

Work with tone on tone fabrics or with few colours.

Do blocks in 2 different colour schemes that work together and combine the pieces.

Strip width and number

You can play with the width of the strips. To keep it symmetric you need to make sure that your outside strips are the same width and the inside strips are the same width as well.

You can use more than 4 strips too as long as they are even numbers and you keep the width symmetric as well.

Note: Since I made this block I’ve been told repeatedly that this technique was developed by the 3 dudes however I have come across earlier examples of this type of block going back to 1989 and Mary Ellen Hopkins and her quilt Hidden wells. Go to google and look up Hidden wells and you’ll see so many quilts using this technique. They’re spectacular.

As you can see the possibilities for this block are quite incredible. The quilt layouts are also varied.

  1. I just love your short and to the point videos. Cannot wait to try this one with scraps? And maybe one solid color strip to tie everything together? Wonder how that will look……..even if I do mine just like yours with all prints, I know I will like the ease of it……..THANKS

  2. Thank you Dottie. I´m very happy you like my short videos. I make them the way I like them so I thought other people may appreciate them too. Good luck with this block. I only tried one fabric combination but your solid and print combination could work out really well. I think this block is very versatile in this way.

  3. Love this! My daughter and me are making hot pads for all the family members for Christmas. We have all kinds from string squares to pinwheels to this now. We made this today & love it. It looks so complex, but super simple. I already have some more cut out for her to sew on tomorrow. If you look this title you gave this up on Pinterest, you are the only one with this. Is there another name for these? Or, did you come up with this on your own?

  4. I actually have no idea if it has a name. I made the name up based on the kind of fabric I used and it being a half square triangle. But I just did a bit of research and It’s probably called 3 dudes. I hope this helps.

  5. Fun! My daughter is just 10, so she is very new to any kind of quilting herself. Right now she is eager to jump in and learn a new square. She felt so proud of this one. I think I may made it as a baby boy quilt soon using some manly fabrics. I know babies like the busy black and white patterns, so that might be a good idea.

  6. That sounds like a plan! Good luck with it! That’s pretty good quilting at 10. She may want to try some disappearing 4 patch blocks too.

  7. Thank you for the tutorial, I’m a beginner and need the easy ones. I need to know how much material I needed, I want to use 4 to 8 fabrics? Thanks again.

  8. Hi Linda, for a block you need 4 strips of fabric each 2 1/2inch x 18 inch? This block is perfect for fat quarters. Fat quarters are usually 18 inch x 22 inch. For 16 blocks and 8 fabrics you will need 8 strips of each fabric. Do you agree?

  9. My math isn’t great but I think that this block will work with any number of strips as long as it’s an even number. So you could use 12 strips 1 1/2 wide.

  10. If I were to buy yardage (instead of using a Jelly Roll), how much of each print would I have to get to make a quilt somewhere between a throw and twin size?

  11. Lisa, My math isn’t great. I don’t want to give you a figure and then be wrong. There’re a number of quilt fabric calculators online you can use.

  13. If you take 4 strips that are 2-1/2 ” each and sew them together with 1/4″ seams, your total should be 8-1/2 inches, not 8-1/4.

  14. That is the math, you’re right. My quilting in the other hand is not as accurate that ‘s why it’s best to measure the piece after sewing to make sure you cut a square if you think your sewing is not 100% accurate
