kblue. I come from a line of women who fret and worry about such things. My mother will still get up and be showered and dressed by 6 if a tradesman is due at 8.30. My grandmother would be pulling a plate out from under you in order to wash it up so she could forget about it.
It's the energy I think that's the nuisance. Like, really, what will it matter as long as you ring early Monday? It won't. It's not like there are elves in the shop sending out orders today. but we think energy wise along those lines and wish the thing was sorted and we didn't have it on our minds! Hence concentrating on the potentially positive aspects - that the shop will know you're honest and trustworthy and so on.
One thing you can do before clicking 'submit' on orders is to print off the order page and check it manually. But, go buy a new mouse!! There are shops open on Sundays to do that!! At least then you will know you're going to prevent worrying all the time when you order.
Now, what ARE you going to do with that yarn. I's such a lovely colour. I like those tans and white combos.
