I need some advise from all you knowledgeable ladies (and the gents out there too).
This weekend I found some fabric I really love. I purchased some along with one of the coordinates in the series to make a purse. After leaving the store my mother and I were talking and I decided I'd like to make a bedroom set out of it (valances, bed skirt, shams etc and of course a quilt!!) DH liked the fabric and the idea of using it in a bed room set so the project is a go. The shop is in a town near my parents so my mother made a trip there today and got me some fqs of the other coordinates in the collection (I think she said there were 5 total fabrics in the collection) and 5yds. (rest of the bolt) of another clearance fabric that also coordinated well with the collection. She's sending me the fqs and a sample of the other so I can see which ones I like/want. All the fabrics in the store are all 25% off for about another 2 weeks so my time is somewhat limited. Now for my question - how much to buy? I have a limited budget or I would buy all she had of at least 3 of them for sure, but I can't afford that. I can figure out what to get for the valance, skirt, etc, but don't know about the quilt. I am wanting a king sized quilt, but don't have a pattern picked out (and probably won't for a little while). How much should I get to ensure I can make a quilt and not be majorly limited on my pattern choices due to lack of yds? Is there a general guideline for this sort of thing?
TIA!!!
