I cut out my
Weekender Bag last week. That was kind of a process since there are a few pieces that only have measurements given, so I made paper templates for them to make cutting a little easier. Plus there are just a lot of pieces, for a bag. And two different interfacings. It was hard keeping track, but then again, I did cut it out while sitting and talking with baby.
Anyway, here's about where I'm at now:

The dots are the lining and piping; the little tree/flower things are the outer.
On Friday I was about to order my zipper. It calls for a 30" and the Treadle employees gave me an order form from
customzips.com. They only do mail order, though, no internet orders, so I went to Amy Butler's website to see if they had a source listed for a 30" zipper. I didn't find one, but instead I found SIX PAGES
of updates for the bag. Eek! I saved the file but didn't print it because F was sleeping.
Yesterday I covered all the piping cord with the bias strips, then I remembered the extra instructions. I printed them out and saw that the update called for a fusible interfacing, which I didn't have. I am generally wary of fusibles.
The point of the fusible is to attach the super-heavy Peltex to the bag fabric without having the bulk of the Peltex in the seams. You cut off the seam allowance from the Peltex entirely, then sandwich it between the bag fabric and a lightweight fusible (cut to full pattern size). That way, you are never sewing through the Peltex, except when you topstitch later. I had to read this a couple times before it made sense, but then I remembered reading a very similar technique in a Kennith King article about tailoring smooth lapels.
The update called for a woven fusible. I was worried about shrinkage. I went back to Treadle and none of my favorite knowledgable employees were there, so I talked with someone else; she wasn't really sure what I needed but was helpful anyway. I ended up with a lightweight non-woven fusible.
Or so I thought. I pre-washed it in a sink of warm water and let it drip dry (
Power Sewing's directions). But as it dried, I kept checking it, and I couldn't see any fusible dots anywhere on it. I was so sure I bought fusible, and that lukewarm water could not have washed it all away! But I tested a scrap this morning, and it did not fuse at all. So either I grabbed the wrong bolt or it was mis-labeled.
But I think sew-in will work fine, in fact, I will probably prefer it. I'll just cut off the Peltex seam allowances as directed, then stitch it to the interfacing close to the cut edge, and treat them as a single piece of sew-in interfacing when I attach it to the bag fabric.
I'm excited to actually get sewing on this!
