These are all good considerations, I have always Quilted for enjoyment, that's why pre-finished would be the venu, with selection of colors etc. my choice, can consider it the artist coming out but have seen what some folks pick for coordinating and sometimes shudder at choices, (not mean't to offend) I know there are many great quilters in this area, how much they sell who knows??
Do you think non Quilters know this came from here or there, chances if they did could make themselfs, probibly not your client base, Sad part is saw some at a crafters fair not long ago and was sad to see baby blankets tagged at 35.00 full 125.00 that was just wrong. these wern't eye poppers, but nicely done.
Considering Dbl irish chains, fence rail, log cabins, traditional but not CR issues, other straight line patterns that can be done in a reasonable amount of time.
