Welcome back to the Traverse Bag Sew Along! Today is our prep day when we apply interfacing and make the piping, the straps, and the strap holders.
I'm kind of a stickler for applying interfacing by the book because I've found after years of frustration that I'm not disappointed in the outcome when I spend the time to fuse it properly, so get ready for some pressing!
NOTE* I've also found that the sizing applied to fabrics by the manufacturer don't like to fuse with interfacing. They come off when you wash the fabric, but I often don't wash my bag fabrics because I like the look of unwashed fabric, so you may have to press longer or at a hotter setting to get it to fuse well.
So, here are the steps I use when applying SF101 (ShapeFlex):
- Preheat your iron to cotton (or linen if you're using linen or canvas)
- Press the cut fabric...you want it to be warm.
- Set your interfacing glue side down on the wrong side of the fabric.
- Cover the fabric and interfacing with a press cloth...muslin, silk organza, or even a paper towel will do.
- Spritz the whole shebang with a spray bottle of water.
- Starting on one side of the fabric (IE from left to right, or top to bottom) press firmly for 15 seconds, move the iron over and press firmly for 15 seconds...keep doing this until you've pressed the entire piece.
- Remove the press cloth and give a final press to both sides of the fabric and then check to make sure that the interfacing has fused.
I know that's a lot, but I guarantee you that you'll be happy with your finished product for years to come!
The strap holders are just like the straps, only smaller, so if you're needing more room than your foot will allow, you can always use your zipper foot.
At this point you'll have all your interfacing attached, your piping prepped, your straps made, and your strap holders assembled! YAY!
Check back in on Tuesday to assemble the back exterior and learn to insert a zippered pocket!
