I just wanted to give a bit of an update here:
Everything has been working out great so far. We decided to have all my celebrations (shower, bachlorette, etc) AFTER her wedding so we don't have to try to plan all those with eachother. This way, I also get the summer and fall months for my parties, which are MUCH better weather up here Canada for get-togethers.
I gave my Mom my wedding dress design first and my sister will have to come up with something different. haha.
Also, while she wanted to be married in June, her date is not near my 30th birthday in June, which will obv. be an important celebration for me.
So far, so good! I'll be keeping ya posted!! Thanks for your support ladies!
