First all the furniture/cat food/recycling bags/sewing machine got shoved to the edge of the diningroom which has a laminate floor (highly recommended to quilters as it's ace for taping down backings). Then I had to vacuum about fifty times because we are the crumb and fluffball family and they tend to make their way into the gap between backing and wadding where they show through and reproach me for ever. Do you ever look at housework and think "but didn't I do that already once?"
I will have to investigate other ways (other than to use a basting service:-)) for big quilts, but I do it by taping the backing to the floor all round, then taping the batting at the top, kneeling on the backing and shuffling backwards, spraying a foot section at a time with spraybaste before unrolling the batting and smoothing down. Repeat, until knees are creaking.
The top taped down and ready to go.
By this point I anticipated having to drop everything and clear it all away to collect the children from school but it got done in the end.
Hope the crinkles disappear with quilting! I have a plan but am not sure how implementable it's going to be, given the size.
Sorry for northern hemisphere winter indoor photos. I'm linking up to Finish it up Friday (Hooray!) even if I can't get a decent photo without taking it outside and dragging it in the mud.
