In my first apron, I actually sewed the criss-cross straps to the waist, and the ties were sewn on separately, so it wasn't very adjustable.
Then I realized I could make it more adjustable by simply having the criss cross straps go through a buttonhole on the waist, and then tie. That's how this one is done:
Blue and Yellow Floral/Gingham 1
(Because this was still an "experimental phase" apron that has buttonholes instead of D-rings, I'm reducing the price to $25.)
A closeup of the fabric, it's a bit hard to see but the gingham is blue and yellow:
I thought the buttonhole was good, but then I decided to simply sew a D ring on each side for the straps to go through, which I thought gave it a nicer finish. The rest are all using D rings.
Country Blue and White Floral - SOLD
(Ok I admit it...this one is my fave. Red is just my weakness...)
All of these (but the first, which is $25) are $35 each, plus shipping. Email me at mllevaleur(at)hotmail(dot)com if interested! I'm also willing to do customized aprons, if any of these spark a different idea or color scheme you'd like!
UPDATE: Most of the ones listed above have been sold now, but keep an eye on my Etsy Shop for more coming soon!
