Other suppliers are available Just remember to set the printer to do it backwards or do it backwards yourself, or test it in advance anyway, I was being brain dead first time and looked great ironed it on, and of course it was backwards. D'oh.
The charity weight loss sounds great. I lost 5st quickly and the running has helped keep it off. I found what motivated me was a weekly confessional on twitter and facebook, so each week on x day I posted my weight. I hated doing it (especially early on) but it really helped to motivate me, as frankly I didn't want to have to say i'd gained whilst i was trying to loose the weight
A couple of big studies recently came to the conclusion it doesn't really matter what diet you choose, as long as it's one that you can stick to. I tend to think now that i've been there and done that, that it's not a diet as such. It's a change of lifestyle.
You have to change / break bad habits and replace them with new habits. For instance if you have a sweet tooth like I have. instead of having big bars of chocolate around have more expensive tasty little bars, so instead of eating a big bar of choccie or packet of sweets you eat all of a mini bar. It's not great still but it's better than before.
I found what really worked for me was fruit. I know it has calories in, but in my calorie counting I basically didn't count fruit as long as i eat it in it's natural form, so i counted juice etc.. but if i eat a banana or an apple i didn't count that. So i made sure i had fresh fruit around at all times, so if I wanted to snack it was fresh fruit that i had. That really worked well.
Running is awesome it helps to tone you and make you feel better about yourself, when over time you can go further or quicker for the same amount of effort. Don't expect miracles, it will take time to do, but it's really worth it.
