Hello and welcome!

It’s Julia from Inflorescence Designs! I’m so joyful you are visiting today. For today’s tutorial, I am going to share with you how to make my interpretation of the Carpenter Star Quilt.

This quilt is full of half square triangles (HST) and sewing each of them individually can be cumbersome.  To make things easier, I made 4 and 8 HST at a time! I also used Thermoweb’s SpraynBond Fabric Stiffener.  Using the spray made my fabric nice and crisp, which allowed me to easily piece the entire quilt together in ONE DAY!

SpraynBond Fabric Stiffener is a must-have for any fabric crafter! It makes fabrics more paper-like and fray-free for easy cutting, pressing and stitching.

Carpenter Star Quilt with SpraynBond Fabric Stiffener

This quilt measures 46″ x 46″ without the border it would measure 40″ x 40″ It is a nice lap quilt. 



Cutting is specifically for the Carpenter Star design pictured on this post.  Depending on your coloring and design, cuts may change.

The number in parentheses is the number of HST you will make.

HeatnBond Fabric Stiffener

General Directions

  1. Shake well before use! (Turn upside down and shake)
  2. Place fabric on protected surface.
  3. Lightly spray fabric, from 8-10 inches away, until entire surface area is damp. (Do not soak).
  4. To Stiffen: (flat fabric projects) cover with parchment paper and iron on medium heat until dry. Let cool.
  5. To Shape: Create desired shape and let air dry.
  6. If fabric needs to be stiffer, repeat steps above.

Quilt Construction:

Once all your HST are constructed, it is time to assemble the quilt.  Assemble your quilt using your coloring sheet.  Assemble the sashing.  Once the top is assembled, baste your quilt top, batting and backing together using SpraynBond Basting Adhesive. Once basted, quilt and bind your quilt as desired.

    Great quilt pattern. As soon as I am able, recovering from surgery on a severely broken elbow, I will be creating this quilt as a beach/poolside quilt/blanket. The design allows for plenty of creative color options for a variety of uses.
    I haven’t used the Heat N Bond Fabric Stiffener on any of my quilting projects, but will try it out on this one. Thanks for the inspiration.
