Ok, time for a progress check against my original to do list, and a few to-do's to be added as well.
Tasks for today: Cover 30 buttons and adjust the bust on the mockup to fit better.

Mockups
Before anything else, complete as many mock-ups as necessary to make sure the pattern design and fit is perfect.
Calculate yardages required using perfected mockup DONE (ok, mockups not finished but its close enough)
After purchasing lace, adjust pattern if necessary to place points of scallops over seams.

After writing all that the most daunting thing is the shopping list! Although once I've bought everything, I'll probably change my mind on that.

Finally, I wrote everything on to postit notes and put them onto a calender, to giv

Your wardrobe unlock'd published a article on 'Project planning for success' which seems like a really useful tool, so I'm going to try to run through the steps here as a starting point for the most important project of my life!

1. Define the job in detail
Who:Me! I could share my measurements here but I don't think I will ;)

What:Wedding Dress
Ok, so I can be a bit more specific than that. I want a lace, fishtail dress with short sleeves and buttons up the back. I want something that offers light support (i.e. flattens my tummy) without smooshing my natural curves. In fact, I have found (and tried on) the almost perfect dress, Festin by Pronovias. 
When:No wedding date set so I'm giving myself till May 31st
Where:Aldershot LDS Chapel, possibly the London Temple
Why:Because I can make something that is both modest and sexy without having to add a jacket. Because I can get more for my money. But mostly because its important to me to do this, sewing is part of who I am and buying a dress just didn't feel right, regardless of how much stress it would save me!
How:Good question! With very careful time planning, lots of mock ups, and a 3 day course in bridal sewing next week. Reading the book 'Bridal Couture' by Susan Khalje. Lurking on bridal sewing forums. And if it all goes wrong, I am prepared to admit I need help and find a local dressmaker to help with fitting and/or finish the job!

The main question still to be answered is whether or not the dress will be beaded/sequinned. I loved the amount of sparkle the dress I tried on had, and my HTB is a bit of a magpie - he loves sparkly stuff! If I don't go for the sparkly option, I may end up with a dress I can also wear in the temple (with added long sleeves/neckline filler). And of course, it depends on the laces I can a) find and b) afford.
