if i can say just my two cents even with permission to make a pattern you need to ask the artist to make sure that if it just for your personnal use they might not want it to go public where as some can make a profile off there image. i got permisson from jan brett to use some of her stuff but with discussing this with some other if they was to use the pattern and sell finished project that might be subject to copy right . so far i haven't gotten a responce back from jan brett to find out if that would be ok thats why i haven't used any of hers so be careful and make sure what permission you get what it covers. thats just my two cent better afe that sorry
