Using HeatnBond Iron-On Vinyl to sew a waterproof snack bag

Yesterday, I introduced you to the sewing products we’re using this week. HeatnBond Iron-On Vinyl and Odif Odicoat Gel Coating are new products for me, so I’m looking forward to using them on some quick, waterproof items that are perfect for use outside in the summer. The instructions for using the iron-on vinyl are included with the product, but I’ll go through them, step by step, so you see how it’s done.

Instructions for using HeatnBond Iron-On Vinyl

We’ll start by making this little snack bag that measures 7″ x 8″.

Set your Oliso Pro TG1600 Pro Plus Smart Iron to medium heat with no steam.

Peel the vinyl from the protective paper and place it, sticky side down, on the wrong side of the fabric.

Place HeatnBond Iron-On Vinyl on fabric.

  • Press and hold the iron on the protective paper for 8 seconds. Repeat until the entire surface is laminated. Don᾽t touch the iron directly to the vinyl.
  • Turn the fabric over. Press and hold the iron on the back for 4 seconds. Repeat until the entire surface is heated.
  • Apply another piece of HeatnBond Iron-On Vinyl on the right side of the fabric, following the directions above. You now have a piece of waterproof fabric with vinyl on both sides.
  • When the fabric has cooled, trim it to 8″ x 17″.

Putting it all together

  • Measure 7″ down from the stitched short edge for the bottom fold. Draw a line with a chalk marker if desired.
  • Fold on the drawn line with wrong sides together. You’ll have a little flap that’s about 3″ deep at the top.
  • Round the corners of the flap piece using scissors or leave them straight.
  • Stitch across the other short edge using a SCHMETZ Denim Needle size 90/14 and a walking, even feed or Teflon foot on your machine. Stitch ¼” from the outside edge.
  • Fold fabric on the drawn fold line, wrong sides together.
  • Holding the sides together with UNIQUE Quilting Clever Clips, sew from the bottom fold, up the side, across the top and down the other side. Use a 2.5mm stitch length and sew with a ¼” seam allowance. Back stitch at the beginning and end of seams.

Use UNIQUE Quilting Clever Clips to hold fabric in place for sewing.
